True story:

A man held up a small grocery store here in Arizona (we have concealed carry gun permits here). The clerk held at gunpoint with his hands in the air, smiled, and told the gunman - "before you do anything that you might regret, you should probably turn around VERY SLOWLY." As the gunman turned around he saw four customers with their own guns aimed directly at him. He dropped his weapon and he was held for police.

Crooks hate it when the good guys can fight back on their terms and win!

I have my concealed carry permit. I know all the rules. I carry a Glock .45. Hopefully I will never have to use it to defend my wife or I.
But... I will if I have to...
