Guns Studies and Politics
The two seem to be inseparable:
What Researchers Learned About Gun Violence Before Congress Killed Funding
I found the article... irritating, in many ways. Too much speculation and "What Ifs". Yet, I would be just about ready to give up reading it, when it would say something very reasonable or thoughtful.
Any such future study would be incomplete without also looking at countries that have strict gun control laws, and the impact of such laws on crime. The worst assertion in the article was that homes with guns were not safer than homes without. Gun protected homes that don't experience crime because they are protected, don't show up in statistics. Anyway, there is plenty of food for thought. As some of the comments following the article show. It will always be a contentious topic.
