Seems to me that a smart cop would just start looking for a Black guy at every crime scene.
LOL! Once, when I worked at a middle school, a kid was complaining about being hit in the face in the hallway. The principal asked for a description of the offender. The kid started out with "he was black". The principal stopped him right there and said "what does his skin color have to do with this?". Arrrggghh!
