I don't think this was really a disturbance, per se. The title of the video is "Disco Party In A Police Station Prank." The group was praising their police department in rap. The Officer with the shaved head was smiling all the while he was talking to the rapper in red shorts. The Policewoman in the back ground looked like she was trying to stifle a smile. Apparently, they were asked to leave and the group left without incident.
How else did you expect the police to handle the situation...come at them like gang busters? With weapons drawn? Tell them to get down on their knees with their hands behind their head? Handcuff them and haul them off to jail? There was no wrong doing, here. To my knowledge, no crime was being committed.
Music is the Heartbeat of the World
