If those wondering what is going on. You see protesters marching in Iran, then the motor cycle cops come through hitting people with their batons. Finally a motorcycle get's knocked over. The people light the motorcycle on fire, then rip the uniforms off the cops, pull them aside, give them water, make sure they are okay, and send them on their way.
One more place that's shown it's more civilized than Detroit.
