And I am thinking there are some common fundamental reasons that lead to all acts of violence. I've rhetorically asked previously, "what if Ramos had at least one real friend or mentor"... One could also ask: "What if he wasn't bullied? What if he had better parents? What if he had better teachers and/or counselors? What if he had found a passion in life through sports or religion or art?" The idea that if you hyper-focus on (assuming you could) effectively remove one tool for inflicting such, it would just result in adaptation to different tools and methods with the end result being the same. Doesn't mean that we shouldn't work the AR-15 problem, but focusing on the weapon alone will not solve the underlying problem. And, for clarity, I am with MAS on institutionalizing people, I don't think that is the answer either.
