I am not a gun lover or collector but understand the rights of those who choose to collect and use guns responsibly. Personally I find assault type weapons offensive but my opinion should not trample on the rights of others. That being said, the people who 'misuse' anything (guns, knives, home made bombs, automobiles, vicious trained animals, etc.) to harm other human beings should feel the full force of the law and be subject to severe punishment in the swiftest manner possible. The DEATH PENALTY for mass murderers should be carried out swiftly and to completion. That should begin to slow down anyone thinking of perpetrating such heinous crimes.
