So Greta Thunberg has been arrested in London for holding a placard that said:
'I support the Palestine Action prisoners. I oppose genocide.'
It will be interesting to see if Thunberg's case gets to court because its far from clear that this specific wording articulates support for a proscribed organisation...it may well be a case of [edit] City of London Police over-reach!
In any case its another arrest of a peaceful protestor..
