Earlier quoted context omitted.
The police swerved hard into deploying state capacity against exactly the wrong people: https://www.telegraph.co.uk/news/2026/03/12/more-women-arres... Meanwhile ignoring the actually violent far right to the point that we had arson attacks in Belfast and a stabbing spree killer in Edinburgh.
Police has no choice but to arrest people who commit a serious criminal offence on purpose and very publicly. It would undermine their credibility and the rule of law not to arrest them. This is orthogonal with how police should tackle the violence you mention. Edit in response to @pjc50's replay below: The signs are a serious criminal offence. Supporting a proscribed terror organisation is a serious criminal offence…
This was literally a decision Starmer personally made, to put Palestine Action on the proscribed organization list. Without that the signs would not be an offence.
