Simply an amazing video. I wonder what possessed this pack to dash out onto a freeway en masse? They don't seem the least bit concerned with either the pedestrians or the moving vehicles. Check it out.
Of course, the fact that the pulled over vehicle has its own POV (the passenger shooting his own video of something as innocuous as a traffic violation) gives one pause as to the authenticity of this event. Comments over at Boing Boing indicate that this was a staged event.
