Really? Because my best friend is paranoid schizophrenic, and not once has she ever been violent to the point where I wish I had a gun on me. Sure, she's stopped taking her meds for awhile, and during that time she had freaked out when I'm around. However it was not so serious that she needed to get tased and trucked off to a loony bin (though it took quite a bit of convincing that her meds, while not enjoyable, were the best option at the moment). In fact, the only times she went to the hospital were for issues more or less unrelated to her schizophrenia.
The state of the mental health system in the US is appalling quite frankly. There hasn't been much progress in the way of treating the root causes of issues like schizophrenia and bipolar disorder, even though we know what causes them (albeit, the whole "blood-brain barrier" thing is quite the hurdle to leap). To boot, I feel like the government and the people have more or less given up on mental health, with the prevailing sentiment being "oh, just throw them in a hospital and it'll be all better". And while there are cases in which long-term stays in mental health facilities are the best option, it should not be the only option.
Improvement in mental health facilities and care is something I care strongly about, and that I agree wholeheartedly with. It's a good solution, but not the only solution. Stepping up background checks and records of gun owners in the US, along with giving the ATF the ability to do its job and regulate firearms (hence: Alcohol, Tobacco and Firearms), something it currently cannot do. Again, I'm not saying "WE SHOULD BAN ALL GUNS", which has been suggested by certain members here on AE. I say we need to get smarter about guns. However, guns and mental health are not the only issues that factor into senseless gun crime in the US.
Fun fact: For the past several decades, the total amount of crime has decreased significantly. However, conversely, the rate at which crime is reported, the number of news stories featuring crime, as well as gun ownership has increased dramatically. Why? Well, it is my theory, and the theory of others, that mass corporate media, in a bid to increase viewership, has stepped up efforts to put out fear-inducing stories. Again, why? Well, sex and violence sell, and news companies are businesses looking to sell. Fear keeps people buying, which makes their advertisers happy. But I'm going off into paranoid speculation, and nobody likes that realm
Others will point to violent media, violent video games, violent music, and the claim that we have a naturally violent culture dating back to the Pilgrims and such. However other countries have violent movies like Die Hard and Rambo. Germany is universally accepted as the home of violent death metal (Rammstein, anyone?), but the country has 0.8 murders per 100,000 people annually. Japan invented ultra-violent games like Mortal Kombat, and that nation has 0.4 murders per 100,000 people. And as per the claim that we are an inherently violent people, again other countries have equally violent forms of media.
So what makes us different? Well, who knows? Honestly there is no one clear cut solution to reducing gun crime. Maybe pumping more funding into mental health and law enforcement will help. Maybe banning guns in general will help (probably not), or maybe banning certain guns will help. Point being, there is no 100% clear cut solution to gun control, and we should not be so quick to point fingers at one particular "issue". I rest my case.
