That's a good point.

I think they meet the definition of "terrorists" by their stated goals and acts. But it seems there's reticence by the CPS to break out the Terrorism Act.

Palestine Action is already a proscribed group because of spraypainting RAF planes. I would say this raid seems more terroristic than base invasion, but what do I know? I'm not the Home Secretary.

It raises questions, because while the Terrorism Act is heavily criticised for being overbroad and making a number of otherwise innocuous things crimes, the CPS haven't used it against this group of people, who'd face prison just for being a member, or claiming to be a member of Palestine Action. Maybe the CPS can't reliably prove they are?
