Hmmm,
I have never stopped and searched a black person. A few asians but no blacks. I have stopped and searched literally hundreds of white people, most of whom adhere strictly to the skag-fast diet.
Funnily enough most of the crimes in the area I work (Just outside Glasgow, one of the most deprived in Scotland, even Cabletel refused to cable the place as they'd probably have nicked the copper from the cables) are committed by the pale, skinny, white intravenous drug user and maybe I'm stereotyping but given a choice between stop searching a couple of junkies and an old grannie I'll take the junkie option every time.
Maybe I'm just biased coz I don't like them.
I have been accused of being a dirty orange *bleep* or a dirty fenian *bleep* but I suppose thats just the West of Scotland mentality.
The Police aren't racist for going after a certain group if they are responsible for more crimes in an area. It's common sense policing.
If they want to wonder why certain groups are more likely to be involved in crime thats a different debate altogether.
