From what I have read, the a large proportion are gang related. That the point being made by many here who objected to legislation that would affect the generally law abiding. They do not cause much of the problem and there is already legislation that allows the police to get guns of criminals and gang members. They just need to start properly enforcing it and the supply needs to be dried up.
I then realised that was going to be pretty much impossible to achieve, so the USA has to just develop coping strategies.
You could blame gangs, which would cover most gun violence, maybe even 60 or 70%. Or you could blame men, which would cover more than 95% of mass shootings.
As a man I find this very disturbing. This is an American problem, but it is a problem caused almost entirely by one half of America, American men.
Should it be much harder for men to buy guns in America?
