This topic was started to discuss responsible gun control, but inevitably it's swung around to the event/s that prompted the discussion of gun control in the first place. This isn't a bad thing, since the two are related.
First, I think it's not a good idea to be talking about gun control immediately after a tragedy such as this. Laws should be crafted carefully, and intelligently; when people are behaving with fear and emotion, good legislation cannot result. What we need to do right now is deal with the tragedy and it's results. And move on.
Second, it's interesting to look at the history of violence, and instructive. Someone brought up that Bath tragedy, over 80 years ago. Violence isn't a new thing. Humans are violent, and I don't think that'll ever change. But something has changed, and that is, ironically enough, the very thing that is allowing me to make this post that will likely be read by dozens of people. Information dissemination has expanded tremendously. We went from spoken word, cave scrawlings, and hand-transcribed manuscripts to what we have today over the course of a few hundred years. Real, mass information dissemination didn't start until the printing press came about, about 1500 A.D. But the whole idea of instantaneous, real-time information is quite new- you might be able to stretch it back to the 1920's or so, with the mass-acceptance of radio. And, of course the internet at everyone's fingertips is a phenomenon of only the past half-dozen years.
Humans have been around for tens of thousands of years.
So now you're combining an ingrained mentality of violence, which we've had since the first humans climbed up on 2 legs and started beating each other with sticks, and the ability to read about it, hear about it, watch it, and become involved in it, which really only happened big time in the past 10 years or so. I'm no philosopher, or psychologist, but it seems like technology is running away from evolution, and we're seeing the results.
Not to mention (bringing this back around tot he gun control debate) the technological advances in weaponry from those first two sticks the first two humans beat each other with, to the weapons that exist today that are capable of vaporizing the entire Planet many, many times over.
How do we deal with this?
