There are idiots that will blame the guns used in this horrific crime but the guns were just a tool. What it all comes down to is this is about a severely disturbed person that was allowed access to the guns (a violation of EXISTING, under enforced, laws BTW) and most likely not allowed access to proper mental health care. There will always be crazy people, and there will always be senseless violence. That is, sadly, part of life. The attacker in China used a knife. are we going to ban knives? Let's focus on getting proper treatment for the mentally ill in our Nation.
