I think you missed my point.  Murders are indeed committed every day, and some people's answer is to ban the weapon, recently "assault weapons" are the current ban target. But what about knives, hammers, fireplace pokers, bricks, ropes, chain saws, automobiles, ashtrays, fists and feet and every other weapon used to murder someone?  The point is, prosecuting the weapon is not the answer, we need to focus on the bad guy and what we can do to bring about changing them - or putting them away.
