this is what it boils down to, great way of simplifying it. people who are against certain weapons, always want some sort of justification on why others want them. some feel there is no explaination required. when it comes down to what someone "needs", its all very subjective. maybe not the most valid comparision, but does anybody need a corvette that goes over 200 mph? no, and while cars and guns are vastly different things, the bottom line is things can go wrong with both so its a valid comparision in a way. to the people who say guns only exist to kill, not true. guns are a means to end a violent confrontation, although killing is a likely outcome.
