Years ago one of my buddies was on the way home when he noticed that he was being followed. He ducked into an alley,parked and got out of the car and hid in a gangway. Sure enough here comes dude who also get's out of his car but has a gun in his hand and is clearly looking for my buddy. A shoot out ensues and the bad guy is killed. Turns out my buddy had arrested the guy a few months earlier.
