This is interesting because in Northern Ireland, even though the UDA & UVF are both banned terrorist organizations, the police will not intervene if you erect flags supporting the UVF or UDA.
UK law is not applied equally across the UK or by the PSNI.
BREAKING: Officers from the Police Service of Northern Ireland (PSNI) are policing the protest against the Palestine Action ban at Trafalgar Square, London.
Wouldn't it have made more sense to not arrest peaceful protestors, like other forces have done? Or lift the ban?
