Actually, I Have said this for years, also you should only be allowed to carry the bullets in the gun on you.
If you break a law then a jury of your peers can convict you.
Guy 1: Hmmm, look at the bad guy who just pulled a gun. ** pulls his own out
Guy 2: Yep. ** pulls his own out.
The Bad guy is now faced with the though of knowing that there are two or more guns point at him ** Note: Training of use would be required, and people would realize that standing in a circle or across from the other guy with a gun is not a good idea **. He also would realize that he would need to face them and all the bullets they have.
