I didn't see the bend but the whole thing was unprofessional. I felt sorry for the bobbies alongside the coach who were in the firing line just in their normal kit. It was negligent because the whole thing was foreseeable and the senior officers failed in their duty of care to City, to their own officers even to those watching on. There were messages on the Internet and fastened to lamp posts in the old fashioned way exhorting dippers to give a 'special' welcome and the intention was to put City of their game.
And of course there was little criticism in the media. As usual l ask what would have happened if the Liverpool bus had been in a similar situation at the Etihad.
