 In 1987, Warschawski was arrested for "providing services for illegal (Palestinian) organizations" and sentenced in 1989 to twenty months in prison, with a 10-month suspended sentence, for typesetting a booklet that the judges ruled had come from members of the Popular Front for the Liberation of Palestine, which described torture and interrogation techniques allegedly employed by Israel's security apparatus, with advice on how to withstand them.The court determined that Warschawsky was unaware of the booklet's origins, but guilty of closing his eyes to the evidence.Warschawski is a writer and journalist, whose articles appear regularly in "International Viewpoint", "Le Monde diplomatique", ZNet, "Monthly Review", "Siné Hebdo" and other publications.
