Nice article. I think the government's time/money/effort would be better spent on improving mental health services. IMO this investment would probably have a better chance of reducing gun violence/deaths in America than the direct regulation of firearms. Mass shootings are obviously terrible.  After one happens, there seems to be a sense that we must "do something".  The problem is that those trying to "do something" don't really appreciate the complex nature of the problem.  Study gun violence, identify the most relevent factor(s), and take meaningful steps to address these factors.
