Yeah, they kept getting acquitted. Part of it was because Elbit and other arm manufacturers don't usually own their premises, but lease them. Meaning the property leasers are the damaged party (or at least one of the main ones) for the occupations and break ins. So lawyers for Palestine Action would demonstrate that Elbit was producing components for weapons that might make the property owners complicit in future war crimes litigation, and naturally those property owners don't want any part of that when they could lease their facilities to some low risk company that just makes buts for forklifts or whatever.

The problem now is that this was so successful that the British state is now going after them with spurious and misused anti-terror charges, where the injured party would be 'the government', they can exclude pretty much any evidence or arguments about international law they want, or just impose such evil and impossible bail conditions on people they can then imprison them for 5 years for breaching bail conditions, like they also have been recently for pro-Palestine journalists.

They have a branch in the US. Palestine Action US along with BDS Boston recently shut down an Elbit factory in Cambridge, Mass.
