Here ya go, say 1 CCW movie goer with a gun is a good enough shoot to hit the Bad guy..... Then cops show up to a shooting incident and see movie goer with a gun... Now what happens...... I would feel for the cop in that situation....
I'm willing to bet that there are far more people carrying firearms thinking they are Clint Eastwood than those who actually know what they are doing.
Shooting a deer in the woods is nothing like what happened in that theater. You better be right, you better be good, and luck better be on your side.
