I don't know exactly what is going on in this video, but there is a huge crowd so Justin Bieber must be in the vicinity.
If you watch the middle of the screen, there appears to be someone jumping a barricade and then you see a swarm of police or security guards. That must have been the incident, I guess he had Bieber Fever!
Not a great video as it appears to be shot from the rooftop of the building across the street.
Anyone think it's strange Bieber is launching a perfume? I thought that was reserved for people like Cher, Elizabeth Taylor and Paris Hilton.
