You come live in the methhead and homeless infested world I was in then you judge. The police admitted they were allowing the homeless to make an encampment on public property next to our county library right behind my house. My wife was incessantly harassed by these people who constantly trespassed. All this while the cops did NOTHING. Did you see their response time with a weapon involved? It's a joke to be an honest citizen man.In your case,, by what you've shared, (I do not know all the details,) instead of confronting the druggie,, you should have called 911, and retreated into your home, instead of allowing yourself be baited into drawing your gun. You became the aggressor by what you said.
The mandated PTI "anger mgt" intake person said he would flat have shot the guy. He also determined I didn't need anger mgt ($45 later).
Keep practicing your reflexes though! May come in handy in the showers!
