As for the even more ludicrous Macpherson Report of 1999, its airy accusation of ‘institutional racism’ against the police was all that was left when it could find no actual evidence of any racially biased conduct.

No doubt the police bungled the investigation of the murder of Stephen Lawrence. They bungle a lot of investigations. But was this because of racial bias? If so, how come they successfully prosecuted three other racially motivated homicides in the same part of London in the same period?
