I'm also sick of hearing how its the illegal gun owners who are the problem. The last few mass shootings here in the USA have been done by legal gun owners. In Vegas, Penn, FL were all done by legally brought guns, 2 of the 3 shootings were by middle age guys who never broke the law until the day they went crazy.
We even got cops down in FL that kill a few before turning the gun on themsleves--one dept had 2 cops in the last few months go crazy with their legal gun.
IMO there is no safe gun owner, anybody could flip out one day and go crazy, doesn't matter who you are or how old you are.
