I know my friend DOF will disagree, but he's not Canadian, so ... :D
Anyway, I can't think of one good reason that anyone needs a handgun. And the arguments of "guns don't kill, people do", and "banning guns only assures that criminals will have them" doesn't wash. I think those who take those positions are intellectually dishonest.
Without banning handguns, there will be no progress. A simple ban is not a complete solution. No one has ever said that. But it is an essential first step.
