Read an opinion piece in the WSJ the other day that I thought had some good ideas. It pointed out that
A University of Chicago study found that only 3% of Windy City gun crimes were committed with legally purchased guns. A federal study in 2004 put the percentage of gun crimes committed with legal guns at 11%. By and large the problem isn’t guns—it’s that people who shouldn’t have them are getting them and using them.
As for mass shootings, almost all of them have involved mentally ill young men. Some used pistols, some used rifles, some had both—but as with street crime, people who shouldn’t have weapons got them.
It suggested three ideas that could help stop gun violence:
1. Dramatically increase penalties for stealing guns. It suggested mandatory 4 year term for illegally possessing firearm and a 6 year term for selling stolen firearm. Make it so burglars avoid taking the victim's gun.
2. Enforce laws against straw purchases. Federal law already makes this a crime punishable by a $250k fine and up to 10 years. This doesn't require a new law, just make it a priority.
3. This one is tricky, but they basically advocated finding a constitutionally permissible way of preventing mentally ill people from acquiring guns. Author didn't offer much of an explanation here.
Anyway, I thought points 1 and 2 made a lot of sense that should be agreeable to everyone. Point 3 is a good aspiration if it can be achieved.
