What bothers me the most is NO ONE in the media ever asks if this or that policy would have prevented these crimes.
In most of the instances of these mass killings background checks would have done nothing to stop them. Most of these killers showed plenty of signs that they were violently insane, however their families had few options for getting them committed or even to report their insanity to prevent them from purchasing weapons. I wonder if there are any stats on the sources of guns that are used to commit crimes. Anyone have any?
