I had the same thing happen in Florida. Home invader broke the front door in. Initially he charged toward me, but he ran when he saw I had a gun.
I was accosted in a Publix parking lot at night a few months ago. 3 bangers emerged from their car (which they left running) and approached me while I was loading groceries into my truck. 2 of them had their hands hidden from view.
Homey #1: "Yo, you got da time?" (probably expecting me to take my eyes off them and look at my wrist)
Me: (Drawing my Glock 20 and keeping it at low ready) "Time to buy a f***ing watch, a**hole!" (never removing my eyes from the 2 whose hands were hidden).
Homey #2: (possibly crapping his pants) "Hey man, we don't want no trouble!"
They ran back to there car and fled at top speed as I took cover behind my truck just in case...
Called the cops and gave a description. The police arrived and told me that there had been a string of robberies the past few weeks from suspects matching the description I gave them. Don't know if they were ever caught, but I am in "Condition Yellow" all the time now.
