I just watched that video above. The cop is a wise ass and the NFL player also handled the situation poorly. The NFL player is understandably upset that he was stopped for running the light but continues to argue and run his mouth the whole time while the cop is talking to him. The cop is much more calm but I didn't like him saying "shut your mouth" either. That would piss me off too.
Overall, its an unfortunate situation. When you are pulled over, you shouldn't argue like this guy did, which escalated the situation. It would have been better if the NFL player said "officer, my Mother-in-law is dying, please allow me go and you can follow me if you'd like to verify". I think the officer should be reprimanded, perhaps suspended, but not forced to leave.
And nowhere did I see anything that implies racism...thats the least debateable part of this. Why was that brought up? Because a white cop pulled over a black citizen? Bad call there.
