I suspect the officer who set that off wishes he'd been a little calmer and patient too.
Which one "set it off?"
One cop says something like "we need to seperate these people for questioning" and then dad says something like "that is not happening." Fight breaks out. I guess I'm not seeing anything that says one officer "set this off." Something happened behind the group to set the fight off, reports are that a derelict threw a punch. Responsibility for this event is squarely on the band of derelicts.
