Of course guns don't prevent crime. What they do is give you a margin of protection in the event an armed criminal decides that he is going to kill you or some innocent person. Like if a prowler is coming into my house, fully aware that I know he's coming in, but he doesn't care because he plans to "take care of me" once he gets inside. In such case I can shoot him and thus save my own life and perhaps others as well.
