Gonzales: Tougher Penalties Deter School Violence?

I can't seem to find a quote on the Web, but this morning, I was listening to radio news and I heard Attorney General Alberto Gonzales talk about the Bush plan to reduce school violence. Gonzales rejected calls for gun control. Instead, an important component of the Bush plan is toughening up the penalties for illegal gun use. Does that really make any sense? Someone brings a gun to school, shoots up a half dozen students, and then kills himself. If only he had known that misuse of guns could get him into serious trouble, he wouldn't have dared?
