No indication it was dark out.
Yes, he may have been wanted but the others never fled so they could be held for questioning. And yes the cops have been suspended for investigation. But cops tend to protect their own.
I am sure it was obvious he was very young. He was NOT the driver so committed no crime, they could pick him up later, if need be. Stopped for expired plate, passenger is not responsible for that. The kid was just "struggling", so a grown man, a trained cop can't handle that without a taser?

What ever happened to 'probable cause'???
