So, there is no doubt now. The court upheld the original decision that Palestine Action is a proscribed terror organisation and support for PA is illegal. No excuses to show support.
It is possible to support Palestinians WIITHOUT the need to support a proscribed terror organisation that's direct action includes assault of a female police officer with a slegehammer and various acts of criminal damage, break in's, damage to UK aircraft.
No one can plead ignorance now if they wave placards supporting proscribed terror organisations they will be arrested. Rightly so.
