Of course some of those that they didn't want there included some of those they would want there..."Mistakes" can be deliberate. The outcome was that a bunch of people the state didn't want there were held captive for the duration of the event, everyone else got a warning that they'd be next if they didn't toe the line. Job done, they now pretend it was a terrible mistake and lob them a few quid in compensation.
I would bet big money that absolutely no individual officer will be held accountable or disciplined in any way. It will be the usual story of "multitude of errors" and "lessons will be learned", .i.e. sweep under the carpet and pretend it never happened.

Bring it on!
