So it appears we have evidence that if we ban guns the resulting massacres would be much less severe
Clearly. But let's just ban the fashion-statement assault rifles, which seem to send a lot of weak brains over the top, somehow.
If we ban all guns, normal people won't be able to shoot home invaders or marauding predator animals, and that would be a problem.
This guy told police he has been fantasizing killing people since he was a child, and he planned this attack out carefully. Apparently nobody knew this about him. What are you really going to do about people like that? It seems hopeless to deal with real madness of this careful, sly kind.
A BUNCH of these characters were known to psychologists/psychiatrists, however, if not to police, and so I think that's where to start. There has to be a lot more communication between psychologists and police about these madmen. Apparently the Colorado psychologist DID tell police about James Holmes, the Batman killer, but they did nothing till he showed up with orange hair and body armor and two assault rifles shooting everyone he could.
This whole process needs to change. If people know about these crazies, I think they simply should be locked up in a mental asylum. It was a terrible mistake to get rid of mental hospitals, just like it was a terrible mistake to legalize assault rifles and high-capacity magazines. There is NO really sane reason to have an assault rifle in America: anyone who does have one is suspect in my eyes for paranoia.
