Deranged lunatics look for the helpless, unaware, and unarmed to attack. It is significant that in almost all of the recent attacks, the villain either kills himself or gives up peacefully once armed lawmen show up. In too many cases the killers should have been in a mental hospital. But in weird logic, instead of changing the law to make it easier to put these people in mental hospitals, we want to change the law to create more unarmed and helpless victims. Finally in a popular video game players get points for going in and shooting up a school. If looking at picture of kids is illegal as child porn, then this should be too as it is worse.
