Holding a sign as a crime, UK

British thugs violently arrested protester Susan White, 74 years old and fragile, for holding some sort of sign. I have not seen a concrete description of what the sign said, but thugs interpreted it as support for Palestine Action. Thus, the act of blackwhiting that declared Palestine Action to be "terrorist" has thus provided an excuse for additional, similar blackwhiting.

Terrorism is a crime. It is fundamentally unjust to label a group (or individual) as "terrorist" without a fair trial.

Ms White has been placed under house arrest, not officially but in a disguised, dishonest fashion: she is forbidden to go to Liverpool Center, but outside her door is Liverpool Center, so she can't leave.

The authorities didn't provide her with a jetpack with which to fly to a point outside Liverpool Center. But I have a feeling she could not use it. She says she has injuries from the attack; I presume she needs to visit clinics and pharmacies. Is that forbidden too?
