In my mind it went down something like this:

Romie: -filming madly while yelling directions to people off-screen-
Crazed protester: -yells as he trips and falls into Romie-
Romie: -jerks back to avoid stepping on people... right into the slightly overweight policeman with a bushy mustache-
Police: -finally have a chance to arrest someone and do so with great glee-
