Well the police officer didn't exactly have any reason to shut down the aftershow. BUT... They were not on public property also and so for all we know he could have been payed to get them off of private property. However... All the police officer said was that he had a family to go home to. Over all I think that Jon was right in the end. Jon could have talked it over with the officer instead of asking to play "one more song" like a child would have done (or in this case a whole bunch of teenagers).
