What to Do About Guns in America?

What do we do about weapons in the United States? 3 things, at minimum---all common sense and not complicated. These won't solve all our problems, no, certainly not but they'll go a long way to curing some of our nation's ills and keeping people from getting shot and/or killed. 1) Require background checks, coast to coast, for ALL weapons purchases, for mental stability and criminal history, 2) Put into law a waiting period for receiving a gun after purchase and 3) Ban assault weapons. Again. Period.
