Whoa! How many mistakes can you make and still live to tell the tale? One, if you know there’s a threat and you have the time, call the cops. THEN deal. Two, don’t deal. What do you own that’s worth your life? A million dollars worth of nose candy? OK, maybe that. Which would certainly disincentivize communication with local law enforcement. (Just thinking out loud.) Although imminent danger of death or grievous bodily harm justifies the use of lethal force, it’s best to avoid that sort of thing when and wherever possible. Three, make your property less attractive to thieves. I’m surprised the tarp didn’t have the words “Enter here” emblazoned across it, multi-lingually speaking. Four . . .
Shoot the bastard. If you’re looking at the business end of a gun, you’re already way behind the decision curve. Five, move! If you’re looking at the business end of a gun it’s looking at you. If you happen upon that situation, happen on out ASAP. There’s more. Suffice it to say, the best way to win a gunfight is, and always will be, not to have one. This guy is lucky to be alive.
