Look folks, the problem is defective people, not guns.

Wrong, wrong, wrong. Defective people can kill. Defective people with guns can kill more, more quickly and more certainly.   Yes, you have to find a way to deal with defective people who want to kill. That doesn't stop you addressing questions of gun ownership, for example by trying to reduce the opportunities of them getting into the hands of the defective people. In fact, the recognition there are such defective people should spur you to look for ways of stopping them getting at the guns.
