KP has absolutely nailed this. More and more of the dossier are being proven to be either futile or bullshit. Alec Stewart has spoken and said he told the ECB that Anderson, Swann and Broad all had access to the parody account. The stuff with Carberry is bollocks, as said by Carberry himself. The stuff with James Taylor is bollocks, as said by Taylor himself and now KP has said it was a private conversation between Flower and KP where he was asked of his opinion of JT (unsurprisingly this found it's way into the media and exaggerated beyond belief, a familiar tale with private conversations involving KP).
In terms of the bullying and cliques, practically every man and his dog seem to know about it but it has been allowed to go on by the ECB, coach and captain. Shazhad has said a player was made to stand up in front of everyone at a team meeting the day after a mistake in the field and apologise. Hardly the toughness of International sport as it's being made out to be by the clique, more an absolute case of bullying. If this is in anyway related to Trott's illness then the ECB, coach, management and everyone else involved should be facing some serious questions.
Finally, for me, the most important thing in all of this is the different reactions to the KP parody account and the text messages sent between KP and Morkel. Imagine you are KP, you are in a locker room with a bullying, cliquey group of senior players who have set up a parody account to take the piss out of you in front of a worldwide audience. These are your teammates and you end up in a room with the coach and captain crying to them because you are so upset about it. They proceed to do absolutely nothing about it, with the help of the ECB. How would you feel the next time you went into that dressing room? And how would you feel about the captain and coach who you poured your heart out to, and they did nothing? Do you think it's at all plausible that you would call one of them a **** in a text message to your mate? I would.
I know that last paragraph is very much the KP side of things but I firmly believe KP had no problem with either Flower or Strauss prior to the parody account. I would say the account, and the subsequent sweeping under the carpet of it (just like they did when Swann criticised him in his own book whilst they were still teammates) is the main reason for Pietersen's attack on Strauss. I know there will be one or two other sides of all of this but that is what I believe as somewhere in the region of the truth. There is absolutely no balance in the behaviour of the ECB so you have to wonder if they have simply just wanted to get rid of him since he was dropped as captain.
Edit: Actually I know KP did have problems with Flower when he was assistant coach but I'm sure they were on good terms for a long time before the parody account.
