Roger Waters, the English rock musician and co-founder of Pink Floyd, has publicly expressed support for Palestine Action, a pro-Palestinian direct-action group recently banned and designated as a terrorist organization by the UK government. Waters criticized the UK Labour government for labeling Palestine Action a terrorist group, describing the decision as a betrayal of justice and democracy and warning it threatens civil liberties. He urged solidarity with the group, calling the situation a "Spartacus moment" against injustice. Following his declarations, Waters faces potential criminal prosecution in the UK. The Campaign Against Anti-Semitism has prepared legal action against him, and counter-terror police have reportedly been notified. Waters maintains that Palestine Action is not a terrorist organization. The Anti-Defamation League (ADL) condemned Waters' support for Palestine Action, citing it as part of his long history of antisemitic and anti-Israel rhetoric. The controversy has drawn responses from various groups, including Israeli lobby organizations calling for prosecution. Waters' stance has sparked debate over civil liberties and the legal implications of supporting proscribed groups in the UK.
