The British police. 

It seems that the young Brazilian electrician who was shot because he was thought to be a terrorist subway bomber . . . (a) was not wearing a heavy jacket, (b) paused to pick up a newspaper on his way to the tube, (c) used his travelcard to pass the barrier, (d) did not run from the police (but ran to catch a train), (e) was not warned to stop by the police, and (f) was restrained before being shot several times in the head.

And the cops lied about it.
