The best gunfight is the one you don't get into. There is a tendency on the part of some folks to think that they can shoot someone, and if
it seems justified, the result will be like in the Old West movies where the sheriff buys the shooter a drink as his deputies carry off the body of the bad guy.
IT DOESN'T WORK THAT WAY and probably never did in the real Old West, either. The law takes killing seriously, and a shooter is not going to be allowed to walk away whistling.
If you carry a gun, you should have an attorney on retainer and have his phone number memorized. (Prisoners don't get to keep their cell phones.)
