I don't know how sound the logic is on drawing against an armed BG, but it worked for this guy.
Shame there's no sound on this. If you look close enough and read their lips I think all the guy did was ask them to change a $20! Jeesh! Cut back on the caffiene buddy!
If you watch close, he draws after he has moved behind the clerk at the counter giving the appearance of moving to help her. He was cool and showed skill. To bad he was such a jerk on the vids he made afterwards.There was also concern that he continued after the BG started to run, but the prosecutor determined that the BG could have been moving to a different shooting position.It turned out the BG had an unloaded gun and no prior record.
