With the response time that the Deputies have in my area, it'll be over by the time they get there. I'll shoot the piece of trash coming into MY HOME TO HURT ME AND MINE. I maybe a tad mistaken but I do believe it's somewhat difficult to dial the phone when someone is shooting/stabbing/bludeoning you to death.
Of course you can always try to reason with someone who's high on meth, crack or coming off the high and needing more. They are always willing to listen to reason. Meth heads are some of the most reasonable people I know.
