3-10x the homicide rate, yes. The US has a printmaking with violence, and the presence of guns makes violent people more effective.

But saying that makes gun owners more violent than non-owners on average is a leap. In fact, if American gun owners were more prone to violence than the average person worldwide, the homicide rate in the US would be way, way worse. The fact that the homicide rate is as low as it is despite the incredible number of guns is incredible.

I'm all for increasing regulation in the right places.

Background checks need to be fixed. Fake IDs have a 100% success rate against NICS because it checks against blacklists but doesn't verify the buyer is a real person. If I want to sell a gun privately, on the other hand, I'm not allowed to run a background check on the potential buyer. WTF?

Straw buyers need to be prosecuted. People who attempt to purchase a gun illegally need to be prosecuted. It's illegal to attempt, but nobody ever gets arrested for it even though there's an FBI record at NICS for the attempt.

The actual guns used in most crimes need to be better regulated. ARs are less than 1%. Cheap, disposable handguns designed to be bought in bulk by straw buyers like the HiPoint C9 ($100 9mm murder gun) need to be taken off the market.

We need to end permitless carry in the states that have it. Licensed handgun owners have been shown to me asking the least likely people to break the law. Preachers, police, and teachers all get convicted of murder at like 10x the rate of a Licensed gun owner. So bring back the licenses.

But more importantly, we need to address the social issues that breed violence. Poverty, social stratification, institutional racism that drives people into gangs and drugs because there's no legitimate path out of poverty.
