Back in 1999, when Hackney resident Harry Stanley was shot dead by the police for carrying a table leg, a black friend of mine commented "They've got away with it so much, they've started doing it to white people".
By 2012, it seems the police had got away with fabricating evidence so much, they were doing it to the Chief Whip. And as with the Stanley case, the police were also leaking supposedly priviliged material to tame journalists, who were willing to reproduce, unquestioningly, the police 'side'.
I don't see the Leveson Inquiry doing much about the police's long term 'spinning' of and in the media. Actually, manipulation is probably a better word than spin. Andrew Mitchell might. Go for it Mr Mitchell.
