As an American, I don't think a total ban on guns is necessary, but I sure would like to see it get a whole lot harder for someone to purchase a gun.
I talk to a pawn shop owner once in a while who tells me that he occasionally has to fill out the paperwork for a prospective gun owner when they are not able to read and complete it for themselves. Last time I talked with this guy, his latest customer could answer "what city do you live in," but did not know what state!
