The Met Police announced late last night that they will resume arrests under Terrorism legislation for people holding signs referencing support for #PalestineAction, despite the High Court ruling in February that the proscription of the group was unlawful.
Rather than admit that the arrest of a woman under the Terrorism Act on March 15th breached their own policy, the Met have now changed the policy to try to make it fit retrospectively. This won't stand up in court, of course.
