Re: SD Question - Pizza Parlor Attack
He said (either on CNN or the local news here), that when she walked to the front of the line, he said to his girlfriend (on the cell phone),"well know it's going to be even longer..." in a voice loud enough for her to hear.
In the interview, he had the same arrogant body language he did in the pizza video...atleast before he got it punched out of him. I think you express it in your post as instinctual recognition. I believe that's how I see it in him. You just know the type.
To me, he was just a want-to-be-tough-guy who got called out.
