I watched a First 48 marathon on TV once and it wasn't until the 5th episode where I finally saw somebody get arrested that wasn't black. Have you noticed that a lot of black dudes behave very similar in the interview room when the detectives leave them alone in the room? They either pull their shirts over their head, or tuck their arms into their shirt like a cocoon, or sit down in the corner of the room all balled up like they're sleeping, or any combination of the above. It's funny how often I see them behave oddly like this.
