Its not racist... and to generalize and say cops are racist is wrong. I come from a family of officers, my BIL is a cop, my MIL is a sgt, my husband is getting ready to go into the academy and thats just to name a few. None of them what-so-ever are racist.
The DRIVER who was 16 was breaking the law, thats why he was put in cuffs, exc. The PASSENGER was not breaking the law which is why he got to go home.
