‘Stand your ground’ cited in shooting of whiny Little Caesars Pizza customer

See, none of this would have been a problem if everyone just carried guns because then a 3rd patron could have shot the 2nd patron for pulling a gun on the 1st patron and then the cashier could have shot the 3rd guy. All without more than 1 or 2 bystanders caught in the crossfire. Problem solved! I don’t get why liberals can’t see this!
