@iclast @rgarner In summary, the Palestine Action group have been proscribed by the UK Government as a terrorist organisation, and as such expressing support for Palestine Action is an offence under the Terrorism Act.

This guy was amongst over 500 people arrested at the weekend during a protest where people were wearing shirts and waving placards with the words "Palestine Action", except in this case the police couldn't read and went off the shape of the words instead.
