Some people can outdraw an aimed gun, lots of people think that they can, I don't even think that I could outdraw a gun in the guy's hand, but if I have a gun aimed at me and I'm certain that he intends to use it, I'm going to very seriously consider trying. Can't run, can't fight, probably about to be shot, all of the options are gone, you try and do what you can.
The smart thing to do is to yell "cheese it, it's the cops!" and kick him in the knee when he turns and yells "Where are they? I don't see no cops!" Yelling "look! Squirrel!" might work around here in dogpatch, but probably not there in arizona. You should yell "Look! Roadrunner!" Maybe that has to go into my mental file of how to get out of trouble.
every situation is unique while at the same time they are all just like little drops of mercury that do whatever they want to do in reaction to any possible outside forces.
Living in arizona you may never have to deal with the frustration of trying to shoot a sumbitch squirrel who knows where you are and just keeps moving around to stay on the back side of the tree. I learned that the best thing to do is keep my dog with me and let him go to the other side of the tree and drive the tree rodent over to my side.
Backup is a great thing to have, whether you are trying to blow a flea infested nut muncher off his acorn maker, or if you have jocko, the lickered up, knuckle dragging, meth making moron from the southernmost end of McDonald county holding his favorite shootin iron in an offensive posture. Now that I think about it, does jocko have any postures that aren't offensive? I dunno.
whether it's a squirrel or a mouth breather, don't give away your trump card. Don't let them see that you are armed. Don't let them see your plans.
A few years back, I saw a guy wearing a black T shirt that said "Don't mess with me, I've got a gun!" It's not going to matter whether he carries empty chamber or not. the bad guy already knows everything.
