They start chewing on the twigs in the morning and by afternoon they're really agitated and looking for trouble, usually popping off their AK's or whacking each other with machettes.
That's one of the problems with the Blackhawk Down deal. It occurred when the A-wipes were at the height of their agitated state. Don't know about the 44 mag angle but people that are A-wipes by disposition plus whacked out do not respond to pain stimulus like "normal" people.
Last night I was watching one of those police video shows. A very enraged and stocky build guy with a shotgun took a hit in the shoulder from a 308 at 110 yards. The bullet glanced off the shotgun barrel and obviously hit him in the right shoulder. The guy fell down but bounced right back up. He surrendered a day later.
When people are psyched out and/or full of adrenaline all bets are off.
