He didn't run the cunt over because as Commissioner, he's no longer a policeman, he's a politician, and he realised that as soon as the BBC and the Guardian got hold of the story, poor mr masood would be revealed to have a long history of mental illness, and the fact that he's gone berserk and stabbed people screaming "alahu akbar!" has absolutely nothing to do with him being Muslim, it's just a fucking coincidence that the last 1000 or so 'mentally ill' people who went berserk and killed people whilst shouting about allah, are all fucking Muslims too. Running him over would have been a cowardly attack on a vulnerable member of society.
That's what he thought.. Me, I would have reversed back slowly with the door open so I could watch his cunting head go like a crimson coconut.
