I will write again. There can be a mass shooting every single day in America and nothing will change. You can't disarm 100+ million people with 270+ million guns. It is impossible. America not only has a large gun ownership population but has a huge land mass. It isn't a small country.
It is the same reason it isn't feasible to try and deport all the illegals in America. It is a number game. It is impossible to round up 12+ million people and deport them. If we can't do that, than we surely can't round up 270+ million guns. Keep in mind there is no digital national database of registered guns. I own several and there is absolutely no way to trace those guns to me, and I bought them legally.
I'm for gun laws and more gun controls, but I don't see them having any real impact. The only solution is the complete ban of guns, and that will not happen in America. Guns are part of our culture.
