First off, I am fine with the current legislation being modified, or scrapped and replaced. I think we could totally use an vastly updated system that comprehensively deals with firearms, and more thoroughly codifies our rights and our responsibilities regarding firearms.
However, when we're discussing the current proposal, I can't help but think that it is being proposed purely as an emotional response to a tragedy. It's basically like banning 'pit bulls' because they are scary looking. The death toll of the entire rifle category, including the AR-15, is not nearly significant enough to warrant ANY legislation. It amounts to a rounding error.
The other key aspect, the magazine-capacity portion, is equally silly. The Newtown shooter had what, 20 minutes, before an armed response arrived? The VaTech shooter picked infinitely more able targets and took down more people with smaller magazines. Unless we legislate back to black powder, magazine size is going to make VERY little difference.
Also, while tragedies obviously focus our attention more sharply, we ignore the causes of death that are equally preventable through legislation, yet occur in one's and two's. The pain felt, though, is no different. I have a fairly unique perspective, as I graduated from Chardon High School, and my grandmother on my mom's side spent the last 55 years of her life in a wheel chair after being plowed by a drunk driver. Death is obviously worse than paralysis, but it still sent 5 kids into fairly abusive foster homes. We could as easily take steps to stall out drunk driving, which is a bigger problem, but they might inconvenience people, so we won't.
If we're unwilling as a nation to inconvenience people when it comes to a privilege, how can we make the argument that we should inconvenience or ban people from something that is a right?
Hell, if we want to isolate alcohol... It is much more popular, causes many times more damage to society, and only serves one purpose (recreation). Lots of people buy it legally, and somehow much of it ends up in the hands of people who couldn't legally possess or drink it. Through its' use, 10,000+ people a year die just from DUI's, another 4,000 die from alcohol poisoning, still more die from long-term overuse, and on top of that, all too many families are destroyed (or started ) through it's abuse. Yet, in the face of all that, we maintain a status quo in regards to legislation surrounding it. We don't require alcoholics to register their beers. We don't require drinkers with children to keep a beer safe. We don't mandate people convicted of DUI to abstain. We don't make you go through a 100-hour beer school before granting you a beer permit.
Lastly, over the last 20-30 years, crime has dropped precipitously throughout the country. The vast majority of our gun crime takes place in cities of greater than 250,000 people. Noticing that trend, which extends to many crimes other than just those involving guns, I would suggest that the legislation needed has less to do with guns, and more to do with the environment of hopeless despair in those areas, and the relative acceptance of crime by their populations. On the other side of that, though, I would be very interested to see the mass shooting stats of just inner-city schools over the last 30 years or so. While they happen rarely enough to be almost anecdotal, it seems mass shootings are largely a white man's gig, excepting of course, the AZN over-achiever at VT.
