No...that is criminal carnage, and how many of those doing the shooting are felons with prior weapons convictions let out of jail by democrats? That is the real problem, not normal, law abiding gun owners who have guns for self defense.
Again, almost every mass shooter had no criminal record.
Holmes, - No criminal record.
Cho - No criminal record
Lanza - No criminal record
Paddock - No Criminal Record
Mateen- No Criminal Record
Cruz - No Criminal Record.
Loughner - No Criminal Record
The only guy with a "Criminal" record was Kelley, who shot up that church, and that was a domestic violence beef.
Second issue- yes, violent felons are able to get guns despite not being able to buy them because they can borrow, steal or acquire them from someone who can get them legally. That's the problem when you treat gun ownership as a "right".
