you think that but just wait until it happens.
we have law enforcement because of many things. people do steal, people do kill and people will kill to survive.
so to make everything just, there is the law.
wouldn't you want some justification if you were hit by a drunk driver and was paralyzed for the rest of your life? the cops are the first ones there.
oh and i definitely DO NOT think everybody should have a gun. we'd all try to be a bunch of cowboys.
a gun in the hands of the wrong person could do much damage. that's why there are laws for guns.
