I often provide this example when stating why I believe we should uphold the constitution in its word for word form and continue the right to bare arms. Its a two part deal so bare with me...

If you make guns illegal, the bad guys will still have them...and there is nothing you or I can do about it because we dont want to go to jail for getting one too in order to defend ourselves.

With guns being legal, I like the idea of being in a location where some madman comes in with a gun waving around killing people. Only because I know their is a real good chance that someone else in their has one too and is probrably a better shot with it than the madman.
