It would appear that the Police are now intent on getting in early and stopping protest. I won't go into a discussion about whether this makes the UK a 'Police State' - I will suggest instead that you read the parable about boiling frogs...
What this will mean for protest in the UK?
My concern is that it will inevitably mean the formation of smaller cells of activists. Getting 114 people together means trusting many of them in advance with some degree of detail. Either this was leaked to the police, or the number of messages between known activists directed them. So the logic is to work in smaller cells.
This has huge risks.
Large groups tend to be more moderate - in my opinion and experience. In smaller groups there is less likely to be someone to moderate extreme thoughts and opinions, and dissenters may be easier persuaded.
So is this the police plan?
Who can tell, could be cock-up or conspiracy.
If you want further reading, may I suggest The Man Who Was Thursday: A Nightmare, a novel by G.K.Chesterton, where all of the key anarchist conspirators, except one, are undercover detectives.
