I am still trying to make sense of the whole affair - was it a little spat which got out of hand or was it, as has now been alleged, an attempt to "fit up" Andrew Mitchell?
Neither option seems particularly credible to me. Mitchell admits to swearing at the police, but not using the word "pleb". I'm quite sure that this would not have been the first time that someone had swore at the police officers concerned and I fail to see their objection to the word "pleb" - I'm quite sure that far worse words would have been used against them when they were beat officers on routine duties. Personally, I would have been more offended by the use of swear words, particularly from a a Minister of the Crown, but seemingly these was considered unimportant which I find disappointing.
The suggestion that someone is trying to "fit-up" Andrew Mitchell seems equally unlikely. As far as the public is concerned, Mitchell was a nobody; the public aren't concerned about who is Chief Whip, it doesn't affect them in any way. So why on earth would anyone want to fit him up? Logically, only someone affected by his work would have an interest in doing so, which would be one or more of the hundred or so Tories who have rebelled against the government at some point and thus had their prospective careers curtailed. But collusion with the police - this seems totally improbable even to the most ardent conspiracy theorist.
Other commentators suggest that the Police Federation is behind the whole affair, but why? Surely their target would be Theresa May, the Home Secretary, whom they clearly dislike if one is to judge by their treatment of her at this year's annual meeting of the Federation. But would police officers lie for their Federation? For a mate maybe, but for a federation, no, I wouldn't think so.
