This is the type of guy that probably shouldn't have a firearm. He's so shaken by suspicious people lurking around that he shoots a warning shot to send them away? Get the gun, keep it handy and if the guys threaten you with your life then you think about grabbing a gun. These guys probably would have left him alone if he didn't confront them, but now they won't EVER leave him alone. Stupid move and he deserved to get busted.
