Gun accidents are a tiny fraction of the problem, and therefore even more of a strawman. It might help if TF was open and honest about the nature of the problem he is trying to solve and the evidence he has that his solution would work, but he seems committed to being exactly not those things. So bullet holes it is.
Just no.
Bullet holes are caused by accidents, suicides and deliberately shooting other people.
For accidents and suicides, simply reducing the number of guns would reduce the number of bullet holes (see studies on reduction in number of suicide deaths in the UK when a simple and sure method (gas) was removed). However pro-gun proponents seem reluctant to even admit these as valid arguments.
Deliberately shooting other people is more complex, and brings in arguments about types of guns and owners. This is the argument that Chuck Giteau wants to have, while ignoring the rest of it.
