Ludicrious, as a police officer (and any police officer will state exactly the same), we search persons based on reasonable suspicion. Not on skin colour. I police a predominately white area; therefore, most of my stop searches are on white persons.
It's laughable that people think the police drive around, see a black person and think: "Oh, we better search him because he's black." Searches are conducted for a vast variety of reasons; of which, skin colour definitely isn't one.
