Well its not really a very good analogy you are attempting to draw there AoG, between those arrested through Operation Yewtree and Steven Lawrences brother being unfairly targeted because of the colour of his skin - unless you can show that all of those arrested by Operation Yewtree were white, and were singled out because of their whiteness - which you can't.
It will indeed be interesting to see if he is successful or not.Whenever I hear of such seeming racial bias by the police, I am reminded of the "Constable Savage" sketch :)
