Well in his character profile he describes his characters as a little ball of rage, so I'm just going off the fact that my character would at least be observemt enough to see a guy that looked a lot more angry than any one else.
Truthfully you would have a hard time finding a threat in a crowed based on he looks angry. Maybe he is some dude who just found out his wife is sleeping with the milk man. All so far only 2 Jedi are there and one is out side withvthe protesters and the other is pretending to be a photographer.
