Salt-ish Water in the Household - An Idea to Solve the Coming Water Shortage Problem

Let me preface this post by saying I am blissfully ignorant of the severity of the looming water shortages and its potential solution, but certainly if I was so inclined I might read Blue Covenant by Maude Barlow or When the Rivers Run Dry by Fred Pearce.

Let me start by posing a leading question that hints at my solution:
Do we really need to use freshwater everywhere in the household?

Surely we desire/need/expect freshwater from our tap for drinking and cooking, etc... What I propose is an expanded water infrastructure that allows a household to receive input water of two quality levels: (1) the conventional water we currently get from our tap, and (2) filtered saltwater to be used for other purposes.

What could we possibly use saltwater for in the household, provided pipes and fixtures could handle it?

  1. Watering GMO plants engineered to live off saltwater (bioengineers: start cracking the genetic code of seaweed).
  2. Flushing toilets. This one should be obvious.
  3. Dishwashers and Clothing Washers?
    Perhaps sufficiently filtered saltwater could be used for washing dishes and clothing?
It should be noted that this is a pretty significant change to plumbing infrastructure and might initially be used when retrofitting a population-dense residential building in a city willing to try new crazy things (San Francisco?) or when building net-new residential buildings near a saltwater source.

Bananas by Bicycle - Reflections on My First Time in Uganda

Chapter 1 - Get Your Shots

Early in 2013, I heard about a two-week science policy immersion program in Washington D.C. ran by ASU CSPO. As an enginerd and a long-time politics junkie, wanting to pursue attendance of this rather expensive program I went tin-cupping around campus for funds. Ultimately I was able to get the trip funded 50% by my advisor and 50% by a kind benefactor we shall call Professor S.

A couple months after the D.C. trip I went to Prof S's office to catch up and "kiss the ring".
"What do you think of international travel?" - Prof S.
"I love it. I've been to Europe a few times, Canada a few times..." - Me
"Do you have a current passport?" - Prof S.
"Yep." - Me
"What do you think of Uganda?" - Prof S.
"Uh...maybe not so much." - Me
"You know that's not the politically wise answer." - Prof S.
"Oh, I'm aware." - Me

We meet back up a few weeks later, where I meet Kaitlin, the other student Prof S eagerly wants to ship off to Timbuktu. Prof S mentions Professor Abigail Mechtenberg, who is working on a project related to a solar thermal prototype and that she and her team are headed to Uganda in January to work on it on-site. A bit skeptical of the prospect of shipping off to a developing country in Africa, I offer my gratitude for his considering me to go and mention I know next to nothing about power systems nor solar thermal technology, and that the project may be better served by sending another student that has such experience.
"I don't think you understand the real product of this trip." - Prof S.
"Well I see it as partially a humanitarian effort, so I figure the Ugandans would be best served by a student that has more relevant experience." - Me
"You're the product." - Prof S.
"What?" - Me
"The NSF wants to develop engineers that are leaders and can understand how to work in a developing world." - Prof S.

Now it's starting to click. Of course no one is going to help identify and solve all the energy problems in Uganda in a single trip. Practically the whole point is to provide an invaluable learning experience to the engineers that are sent. Providing any benefit to the local people while there is a secondary or tertiary goal, a concept which at first offends until I recall the "real product" and the long term benefits of the trip.

The meeting ends with Kaitlin and I slated with a list of to-do's including filling out joyous travel forms with the ASU travel office and visiting the ASU health center to get our shots.

A couple weeks later I meet with an M.D. at the ASU health center. Having already performed some research on travel vaccines on the CDC website I already anticipated getting more needles put in me than Keith Richards. The doctor pulls up a map that shows "high risk" areas for various things Noah remembered to bring on the ark like malaria-carrying mosquitoes, yellow fever and typhoid.
"Ha! Great..." - I remark after noticing practically the whole country is 'high risk'.
I leave the office after getting five shots and refrigerated capsules for the typhoid vaccine. In the process I got my first tetanus booster in...30 years or so and my first flu shot ever, because "f it...I'm getting everything else anyway".
Get ALL the shots!

Chapter 2 - "You are SO Lucky."

So Uganda is kinda far away. Eager to get organized to go, Kaitlin and I shop for plane tickets and settle on an exhausting itinerary to get us there: four flights including layovers in Seattle, Amsterdam, and Kigali Rwanda. Tickets get purchased and our first flight is EARLY in the morning on New Year's Day. Like the responsible old man I am, I crash as early as possible New Year's Eve and get up at Oh-Damn-Dark Thirty the next morning and give Kaitlin a wake-up call (turns out she decided to just stay awake after New Year's Eve celebrations...crazy kids).

First flight from Phoenix to Seattle goes perfectly well and we have about four hours until our next flight to Amsterdam wherein we have a two hour layover. The Seattle to Amsterdam flight takes off about one hour late...(cue sad/dramatic foreshadowing music). After watching what felt like 13 movies and having about 8 meals on our Airbus A330, Kaitlin and I begin to worry about catching our next flight. We are near the back of the enormous aircraft that holds about 300 passengers. Ultimately we realize we'll debark calmly, find the gate for our connecting flight and RUN. We find a screen with departures and I gaze at it stupidly, attempting to decipher it with my 0 hours of Dutch language training. "How the f**k is this thing organized..." I think while hopelessly looking at the screen. Finally realizing it's organized by departure time, ascending "What the f**k..." we find our flight and see that our gate is only one concourse over. We sprint. We make it to the gate and meet Dr. Mechtenberg and her merry gang of students, and we're off to Kigali, Rwanda. Eight hours later we're parked at a gate, remaining on board for passengers headed to Uganda.

From Kigali it's only an hour or so and we finally arrive at Entebbe airport around 10 pm local time. We get through customs and head to the baggage carousel. Generally I ALWAYS carry on all my luggage to mitigate the disaster about to unfold. I look helplessly at the baggage carousel and after the rest of the party happily stands by with all their baggage and a near-empty carousel mocks me, reality sets in. Sweet, I'm in a third world country in Africa and don't have my luggage.

I shuffle over to the 'lost baggage' desk, and begin to enjoy the unorganized chaos. I am not the only hopeless traveler crowding around the desk as others also had a tight connection in Amsterdam. Don't look for a 'take a number' machine. Don't look for an organized line. Just accept the madness. Hakuna Matata. It's about 45 minutes until I finally move my way into an available spot and present my passport, baggage claim ticket and boarding passes. The 30+ minute experience being helped motivates me to make this public service announcement... If you work at such a customer service desk wherein each customer will be with you for a while...keep them updated on what's going on. Don't make me pry. Ultimately I learn that, sure enough my luggage is still chilling out in Amsterdam (I hope it found a nice 'coffee shop' at which to hang), and that the bag would be sent on the next flight. The next flight is tomorrow, arriving at the same about 22 hours away. Baggage delivery is during the day. I am provided with a stack of helpful information including the lost bag desk's direct phone number, my reference number, etc... So now my best hope is that my luggage with my clean clothing and other essentials will arrive sometime two days later. Until then, I'm left with the clothes on my back, the one pair of underwear I've already enjoyed for ~ 30 hours, and various crap in my carry-on bag.

We head out of the airport to our taxi-service mini-van, piling in the ~ 10 of us and "most" of our luggage. Shortly after loading up, Dr. Mechtenberg suggests the prospect of buying a replacement custom-tailored wardrobe...just in case. The prospect amuses, but I just desperately want to hug my luggage. She asks if there was anything very important in my bag.
" Malarone (anti-malaria medication)."
"Ok!!! Does anyone have extra Malarone?" - Abigail Mechtenberg calls out to the other students.
A quick inventory suggests everyone will have enough even if I have to bum from other people every day. It's about a one hour drive from Entebbe to the capital city Kampala. A drive that freaked me out...quite a bit. It's about one in the morning and our driver flies down dirt roads continually passing "slower" drivers and while never actually killing us in a head-on collision, doesn't exactly avoid the possibility either.

We eventually arrive, unscathed, at the Pope Paul Memorial Hotel in Kampala at some unknown hour in the wee morning, and I happily fall asleep for the very first time under a mosquito net.
The next morning I hand-wash my one pair of underwear and one of the two shirts I was wearing, and meet everyone else for breakfast. A rather helpful poster is displayed prominently in our hotel's lobby:

After breakfast we decide to head into downtown Kampala for various errands, including potentially buying some clean clothes (I'm sure there are plenty of 6'0" tall, 260 lb guys in Uganda, so this should be easy...). 

Traffic in Kampala is...well exactly what you might expect in a big city of a developing country. Most of the vehicles on the road were either large taxis (vans that would carry about 14 people) or motorcycle taxis (boda-bodas). The former British colony incorporates a lot of roundabouts and "driving on the wrong side of the road". Traffic lights are practically nowhere. Honking your horn actually has meaning and effectiveness in this African wonderland, as we watch boda-bodas and bicycles move over time and time again to make room for our taxi-van.

Lawrence, a local friend of Abigail's acted as our chaperone in the area for the afternoon. I couldn't help but admire his stylish sandals:

We first stop at an arts-and-crafts area wherein I could easily lose/leave my mom for several hours (takes mental note of this potential future opportunity). I come back by this area after lunch and miraculously find a couple shirts that fit me.
Arts and Crafts market in Kampala
After the farts-and-craps area, we head to a flea-market full of various mechanical parts to shop for pressure and temperature gauges for the solar thermal system. Let's just say we were likely the only white people (mzungus) strolling around this pleasant market. Truly we were a sight to behold.

That afternoon I make quite a few calls to hear about my delayed bag and continue to hear that the bag 'should' be on the plane that is headed to Entebbe that day. I call again two or three times late at night after the plane arrived and ultimately hear my bag had arrived. Now I pray for prompt delivery the next day.

The next morning after breakfast, the rest of the group heads to Makarere University to talk to engineers and professors working on various energy projects. I stay behind at the hotel to 'smile and dial' to ensure delivery of my precious luggage. I eventually get the cell phone number of the actual driver, and plead with (read 'desperately bribe') him to deliver my bag first in exchange for a cash reward. Now here's what you need to know about Uganda in regards to scheduling. If you have an estimated time for something, add at least an hour or two and then you're close to reality. The Entebbe lost bag desk claims bag delivery occurs during the day from 8:30 am to about 4pm. So...naturally I think 8:30 am is when the bags are loaded up and on the way to their various destinations. Nope. It isn't until some time around noon or later that the bags are finally loaded, because after all, why not wait for another flight to arrive that morning and load even more bags...

My afternoon is a balance of calm patience and crying in a fetal position in the lobby of the hotel. At one point I have one of the hotel managers talk to the driver. The driver spoke English, but the accent is so thick it is hard for our conversation to be fruitful. Around 2:15 pm, Dr. Mechtenberg and crew return from the university. I inform her my bag "should" arrive within 15 minutes. Not two minutes later, I see a van pull up, the driver get out to open the back...and see my bag. Tears of joy would have occurred if I displayed emotions like humans tend to. "You are SO lucky," Abigail exclaims. I pause and realize her several years of various trips to Uganda makes this an informed and not passively casual remark.

That afternoon we waited for our ride to Fort Portal, the main town at the west end of Uganda wherein we would call the next couple weeks home. Our hired drivers first arrived with a van far too small for our group, so we waited patiently for a larger vehicle. Note: in Uganda, nothing goes according to your plan. This will be a recurring theme.

Chapter 3 - Why did the elephant cross the road?

We load up into a spacious bus for the five hour trek west to Fort Portal. The road is paved but littered with potholes that would scare a Manhattan cab driver. We stop at a small town about mid-way for "bio break" and to buy chapati (a flatbread that looks like the offspring of naan and tortilla). The brave bio-breakers return from the latrine with stories of the facility that make me grateful for: (1) being a guy and (2) not having to take a leak at the time. It is nighttime when we are about 30-45 minutes away from our final destination when we're driving through a jungle area. Our bus and the other cars slow from our nice cruising speed to a stop. I look ahead to see what the big deal was... Moments later we see a young elephant cross the road. Such a cool incredible sight to see in the wild, and a nice way of welcoming us to the area.

We finally make it to the house of Patrick Kaahwa, a friend of Abigail's and coordinator of USSIA (Uganda Small Scale Industries Association). Patrick welcomes us into his newly-finished house and gets us acquainted. "We have no running water right now because the electricity has been out. When there is electricity, they are able to pump water to get water pressure." Over the days that follow, we learn and accept that intermittent electricity is the norm. In lieu of running water, we are introduced to the 'jerry cans' in our bathrooms. Each of our bathroom has two Jerrycans which hold about 20 liters of water. We also have a bucket with which we can take baths. The Jerrycan water is also used to flush the toilets. Running water, like consistent electricity, is just another luxury that most 'Muricans take for granted. Despite what most Americans may consider substandard living conditions, I get the sense that Patrick is relatively well off in the area. Patrick then introduces us to what must be the Ugandan version of a 'gated community'. He hired a man to keep watch over the house and the land throughout the night, which makes me feel safe and worried at the same time.

We spent the next day having lunch in town at a restaurant called the Dutchess, named so as it is ran by a dutch couple, and a trip to the local market.

Patrick, like most people in Uganda it seems, does not have a refrigerator (yet another convenience we take for granted). The benefit of this, however, is that your food is always prepared with fresh produce.
Abigail and Evelyn chat with Patrick

Later back at home, most of us express interest in learning to cook with Margaret, Patrick's neighbor who acts as our maid and cook the duration of our stay.

Over a dinner of matoke and ground nut soup over rice, we meet John, another coordinator from USSIA, and Peter, an engineer from Makarere.

Chapter 4 - First Day at St. Joseph's Technical Institute
Sign: "This school is a gift of the German people to the people of Uganda - opened Feb 1983"
The next day, we headed to St. Joseph's Technical Institute to meet the technicians with which we'll be working over the next several days. We get a tour of various projects including a grain silo built with local materials and requiring zero energy to keep the grain or maize aerated.
Grain Silo at SJTI
It should be noted that other well-financed mzungus have tried to engineer something similar for the Ugandan market and have failed miserably.

We then see the various prototypes built by the team over the course of years, including: a 'cattle-go-round' that produces electricity, a bicycle-powered generator, and a hand-crank generator. We then head outside to check out the second in-progress prototype solar thermal trough on which most of the attention will be focused during our stay.
The team inspects solar thermal trough prototype # 2
Before coming to Uganda, I knew very little about solar trough systems but wanted to be as valuable as possible to the team. So the first few days working with Amos (the de-facto team lead in Abigail's group) was for me a delicate balancing act between my tendency to assume control of every project, and yielding to Amos's relative expertise on various topics. At very least, I just didn't want to give off the impression that "the PV guy is trying to sabotage the solar thermal system".

Chapter 5 - Field Trip to Crater Valley Kibale (CVK)
CVK is the site wherein the St. Joseph's techs installed a hydroelectric system. The CVK lodge is on a lake and like most of the area is incredibly beautiful. The trip was in part for the sake of sightseeing and also for maintenance as the system was known to be down before we arrived. The techs got the problem solved in short order upon arrival. The conversation about the formerly out-of-order hydroelectric system between the frustrated owner of the lodge and the technicians felt remarkably familiar to me. I was reminiscent of several years arguing with other directors about the function and performance of various software applications.

A short walk from the lodge let us "monkey" around.

After lunch, we walked down the road and to the river where the hydroelectric system was installed.

Chapter 6 - Back to the Drawing Board
For several days, we worked under the assumption that the prototype solar thermal trough was essentially parabolic in shape. Running with that assumption, using my Wikipedia skillz, I calculated the appropriate place at which the water-filled pipe should be placed. Days earlier, Amos was attempting to find the focus by visual inspection. His method may have proved more fruitful, and I must admit it first struck me as insufficiently scientific. Ultimately we determined the trough is not parabolic in a couple ways: (1) we couldn't get water to heat up and (2) the method with which the trough was fabricated did not consider parabolic shapes, but rather something more cylindrical. Amos decided to abandon the prototype # 2 trough altogether and had a plan for building a new set of troughs which connected in series would measure about 16 feet long and 20 inches wide. He double-checked his assumptions that evening with our scarce internet, and thus we committed to the bold new path of building a third prototype.

Chapter 7 - Malaria Strikes the Team
About a week into our stay in Uganda, trip leader and student Rainey headed back to Entebbe to escort the latecomer Madeline back to Fort Portal. Rainey had been feeling sick leading up to this trek back east and visited a clinic back in Kampala after picking up Maddie (sp?). I'm sure having a likely malaria-stricken trip leader gave Maddie a great sense of comfort.

Shortly after their arrival in Fort Portal it was determined that Rainey did in fact get malaria, which can be fatal if not treated promptly and appropriately. Rainey spent a number of nights in the hospital in Fort Portal for various treatments. You can imagine Rainey's parents were a bit excited about the prospect of their daughter having malaria in Africa and were on the phone with Abigail regularly. The first treatment consisted of anti-viral pills which had little to no effect. Ultimately she was given I.V.s of quinine. Her mom has a good travel insurance policy and arranged for her to travel back one day earlier than planned while accompanied by a nurse. 

Chapter 8 - Sunday Fun Day
The Sunday of our second weekend in Fort Portal, and a few days before we would head back to Kampala, we had planned on a four hour trek to Queen Elizabeth National Park for a safari. The malaria-stricken Rainey clearly could not come along and Abigail was obligated to stay near her and was not enthused about all the students travelling so far without her. We reached the fair compromise of travelling back to the CVK area, but further than when we traveled to see the hydroelectric plant. The selling points were: less travel time + resort bar hopping + more relaxation time. Surprisingly the whole group was happy with the compromise. I actually expected to have to perform a bit of politicking to get everyone on board with our "plan" to have fun.

At our first stop, we walked down to a lake and enjoyed the view over some Ugandan beers. At our second stop we soon learned the whole place was rented out by one group, but we could stick around for about one drink before we were politely expected to mosey on. I enjoyed a great mojito and another spectacular view and we headed back home for dinner.

Chapter 9 - Let There Be...Properly-Focused Light
We carefully calculated X & Y positions of a parabola 20 inches wide in x dimension. The coordinates for the parabolic curve (as well as the focal point) were scribed onto a piece of steel. Festo, one of the techs, carefully cut out this first side and it became our template for further sides. Over the better part of a day, we fabricated one trough four feet long as a proof-of-concept wherein we would check the focus. Another infamous visual inspection showed promise, and work continued thereafter to construct three additional troughs.

This third prototype trough is incredibly parabolic in shape (especially compared to the first two), and the focus was right on the money. The light was going right where we needed it to.
Light successfully focused on the 16 foot trough
In a last ditch effort to have more successes on the day we planned to head back to Kampala, we put in a half day in the morning to try to get the trough to boil water. Over the course of an hour, we saw the water rise in temperature from about 23 C to 45 C. Around this time, we received the glass covers. The glass was dirty and improperly cut so they did not fit well at all. If the glass was properly sized and the trough was sealed, the air around the pipe would continue to heat up, but instead we were just heating the water in spite of being open to the ambient air. After several minutes of failing to install the glass, which resulted in one of the four panels breaking, we decided to revert back to ambient air. Quietly I think we all knew that moment we abandoned our hope of producing steam before leaving St Joseph's that day.

It will be interesting to see what progress the team makes after we left. With the back mirror properly cleaned and glass installed and sealed, steam may just happen. And with steam is mechanical energy and the ability to spin a turbine to get electricity.

Chapter 10 - Reflections
- The luxuries we take for granted
Imagine walking to your local well or hose, perhaps a kilometer or more away, every day to retrieve the water you'll use to drink, to bathe, to cook, etc... That is a reality that millions and millions of people (perhaps billions?) live in every day. In the U.S. when electricity goes out, it seems the world comes to a halt. In Uganda, it is just a part of life so you deal with it, and that is for the 10% of the population that HAS electricity. When is the last time you washed your clothes by hand and hung them out to dry? What about buying fresh produce that you would use within a couple days before it spoils, for after all you do not have a refrigerator. When did you last cook every meal outside over charcoal? After all, you don't have a stove nor an oven.

- Poor in riches, but not in spirit.
Many of the people I worked with over two weeks make the equivalent of $2 to $3 per day. Let that soak in for a bit. Now granted, a lot of people seem to grow some of their own food and that may cut the food budget somewhat, but still doesn't exactly leave room for "entertainment" in the ol' monthly budget. I am a bit awestruck at how despite what we may consider to be conditions of extreme poverty, how apparently content my new Ugandan friends are. They all seemed to have a rather positive attitude, were productive on the job, etc... I couldn't imagine Americans handling similar living conditions as well, because we have been conditioned differently. Americans are high maintenance. We just are.

- Neocolonialism
To her credit, Abigail advocates for energy systems that can be designed, built, and maintained locally by Ugandans. This may allow, in some ways, greater energy independence vs. importing Chinese-built solar PV panels. However, I must note that on one field trip to the markets of Fort Portal, we learned that solar lighting systems are quickly becoming more common and being adopted by the residential market. Most of these shops would sell about a dozen systems per month, and the most common system included a 15 watt panel, a couple lights, and a battery that supports eight hours of lighting.

- What really matters
Having infrequent access to the internet was simultaneously frustrating but also liberating. I feel the internet can easily become a distraction from what really matters: spending real time with friends and family. I certainly hope here on out that I allocate my time accordingly to this reflection.

Mass-Killings and Guns in America

This post is in response to the shooting on December 14, 2012 wherein 27 people were fatally shot at Sandy Hook Elementary School in Newtown, CT including 20 children.

Over the past few days, I have surveyed an array of different perspectives on this event in particular, gun control in general, and what the real root cause(s) might be, and what effective preventative measure(s) could possibly be taken. The different perspectives were captured on three different Facebook posts (listed below). On each of these posts, I made my best effort to not show any particular bias and to moderate the threads allowing people to post their perspective with no debate.
  1. parents and teachers
  2. people that were either not born in or do not live in the U.S.
  3. U.S. citizens that self-identify as ardent supporters of gun rights.
Here I offer my own perspective, and in typical TMFR fashion, these thoughts may appear to be somewhat organized, yet random and unfiltered.

As an INTJ, my primary concern is naturally the root cause(s) and preventative measure(s) of these tragedies. Before we get to that, a few random thoughts on the 2nd amendment and gun control...

The Second Amendment
"A well regulated militia being necessary to the security of a free state, the right of the people to keep and bear arms shall not be infringed."
  • Consider the primary intent of 'the security of a free state' and the public's resistance at the time to both a standing army and an armed, professional police force.
    • Armed militias were, in part, the solution in lieu of a standing army and police force.
    • We now have both a standing army and an armed, professional police force. 
      • One might argue this modern reality slightly diminishes the need for citizens to be armed.
    • The second amendment was not necessarily intended to let every citizen have an expansive arsenal for little valid reason.
  • One argument I have consistently heard is that we, the people, need to be armed in order to ensure our ability to overthrow a tyrannical government. Let's be completely honest here. If you ever needed to overthrow a tyrannical U.S. government, you would need the help of the U.S. military. Why? Because whatever "arsenal" you think you have at home is a collection of peashooters compared to what we arm the military with.
    • I concede that our government, if tyrannical, should fear that they could be overthrown.
      • However, if an overthrow of the U.S. government was ever necessary, I expect that it would come to pass by a bloodless revolution with mass protests and/or a military coup. 
      • If the executive and legislative branch(es) became truly tyrannical, it is up to the military to remember the "domestic" part of the oath: "...that I will support and defend the Constitution and laws of the United States of America against all enemies, foreign and domestic..."
  • The founding fathers could not have conceived of our modern weapons. In the late 18th century the common rifle was a front-loaded musket, taking 90 seconds to reload. Now we have high-powered rifles with high-capacity clips, armored tanks, armed UAV's, suitcase-size nuclear bombs, etc... Which of these would we prefer to sell at Wal-Mart to individuals with mental illness and/or a criminal record of violent offenses?
  • As wise as they may have been for their day, our all-white-male slave-owning founding fathers were far from perfect. Likewise, the U.S. Constitution is also not perfect, and they knew it. That's why they gave us the ability to improve it.

Gun Control
  • There's a big elephant in the room of gun control, and that is technology. (Damn mechanical engineers...)
      • You can just print out the receiver and buy every other part easily (barrel, stock, clip, etc...).
    • If I'm a crazed degenerate, and have a 3-D printer, it makes no difference what gun control laws you pass. But at least in the short-term, the adoption and usage of 3-D printers is fairly minimal compared to gun stores, gun shops, etc...
  • You're right...guns DON'T kill people, but let's be honest...they make it pretty damn efficient. 
    • There's the saying "Right tool for the right job." If I was a crazed degenerate and wanted to go on a killing spree, what do you think is my weapon of choice: a minigun, or a billy-club? Likewise, you can do a lot more damage with an AR-15 versus a semi-auto pistol. Let's keep it real, people.
  • I think 'Gun Free Zone' signs presented to would-be killers make as much as sense as 'Car Alarm Free Zones' to would-be car thieves or 'Home Security System Free Neighborhood' to would-be burglars.
  • To the whole "criminals" will just get their guns on the black market argument...where do you think those guns come from? There isn't some super-secret underground Willy Wonka gun factory. The gun still ultimately came from a source that legally procured them.

Random Thoughts on Violent Crime and Homicide Statistics: 
  • Rates of violent crime have been steadily decreasing for a couple decades people that feel they always need to be packing heat are a tad paranoid.
  • If we consider all of gun-related homicides in the U.S., you should really consider the statistics by circumstance.
    • Last year there were an estimated 14,612 homicides in the U.S. Only 26 such deaths were in a mass-shooting scenario.
    • While events like the recent shooting(s) are undeniably tragic, they represent a negligible percentage of homicides.
      • I bring up this point so people at least recognize that most gun homicides occur in different scenarios (one-on-one arguments, gang shootings, etc...).
    • Considering that violent crime is continuing to decrease, are we subconsciously allowing the nature of these tragedies to instill a knee-jerk reaction and a false impression of escalated danger?

Root Cause of Such Tragedies 

First and foremost, I feel we need a current comprehensive study into the psychology, lifestyle, and personal circumstances of prior perpetrators in an attempt to find common factors.  If someone can recommend such a recent unbiased study, I would be happy to review it. Until such a study is completed/updated/reviewed/etc...and actually trusted and utilized, we can do some armchair speculation...
  • What is it about the person that makes them want to go on a killing spree?
    • Mental Health Issues?
      • Effectiveness and negative impacts of psychotropic drugs?
      • Difficulty/cost of obtaining mental health services?
    • Sense of Personal Responsibility, or Lack Thereof
    • Desire for Infamy?
      • Sensationalist Media Partially to Blame?
        • If It Bleeds, It Leads.
Preventative Measures - There Is No Single Silver Bullet

Politics is the art of the possible. It is simply not possible to implement idealist solutions, so I will waste close to zero "ink" and brain cells on them. We will never live in a community with zero homicides, zero guns, zero mental illness, perfect parenting, etc...

While speculating on what we might find from an accurate and current study into root cause...
  • Minimize the Recurrence of Such Events
    • Improve access to mental health care? 
      • So who's on board for single-payer health least for mental illness services?
    • Minimize Ease of Access to High-Effect Weapons
      • National standard waiting period.
        • Seriously, you can wait 30 days for your Glock so we can make sure you are not a prior violent felon nor have a history of mental disorder, etc...
      • Psychological examination requirement to purchase
        • It's just a simple, albeit imperfect, fail-safe.
    • New standards on how such events are covered by the media?
      • Basic journalism (documentation of events to a broad audience) has some benefit to society, even when those events are sickening. Besides, as long as we're stating our "favorite" amendments to the U.S. Constitution:
        • "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances." - First Amendment
      • However, these sick bastards are seeking infamy...and we are giving it to them. 
      • Can we somehow report on these events to the extent that we are providing a public service, but keep the perpetrator(s) names and faces confidential to keep them from getting what they sickly desire?
  • Minimize the Damage When Such Events Occur
    • Allow for some solution for bystanders/victims to stop the perpetrator.
      • In grade schools, perhaps we could allow a limited number of teachers to carry firearms. This, however, should be a debate for parents and teachers to have.
        • Perhaps if a teacher desires the ability to incapacitate a perpetrator and is not comfortable with a firearm, s/he could be provided with and trained to use a Taser or a tranquillizer gun?
      • If not teachers, or perhaps in addition to, we could have some armed security presence. A couple professionally-trained police, or former military could suffice. The candidate pool could even be parents or grandparents. 
        • But to what extent do we want this? Police at every school, every shopping mall? This is but a band-aid deterrent and does nothing to mitigate the root cause.
      • New non-lethal options to incapacitate the perpetrator - portable sonic weapons?
        • Maybe it's the enginerd in me...but this would be rad.
    • The following measures might only be effective until 3-D printing is very commonplace. 
      • Ban high-capacity magazines 
        • Recall that the perpetrator who attempted to assassinate Congresswoman Giffords was taken down while he was switching high-capacity (30 round) magazines. If he did not have easy access to such magazines, then he would have had to switch magazines earlier and potentially some life(s) could have been saved.
      • Re-enact ban of high-effect assault weapons

Guns are not the cause of homicides, but they are an efficient and effective tool for killing, and they are not all the same. You cannot honestly say that there is no difference in effectiveness of different guns. If there was no difference, we would still equip the U.S. military with muskets. There IS a difference; we migrated from the M-1 Garand to the M-16 for a reason.

Let us get an updated, accurate consensus on the cause of mass-killing tragedies. Let's trust the conclusions of unbiased experts and implement their recommendations.

Let's end the costly and ineffective drug war. We will effectively eliminating the black market for drugs, minimize drug-related violent crimes, and increase tax revenue (and late-night pizza delivery revenue).

Let us also determine the cause of the decades-long decline in violent crime so we may best ensure this trend continues.
