Chongo, right on. To blame guns for the actions of a few nuts is like blaming cars for killing or maiming 50,000 Americans a year.
What we need is a change of attitude. A killing doesn't start with the availability of a gun, it starts with the desire to harm someone, and a baseball bat, knife or poison will do the job too. I dare say most of us would like to harm someone, but we are able to control the desire and weigh the consequences. Those nut cases lack the impulse control that most of us have.
