UK arrested Tommy Robinson for reporting child-rape gangs that the government caters to. The UK banned reporting of his arrest, denied him a lawyer, and is trying to have him assassinated in prison. Regardless of how you feel about his views, this is a totalitarian government.
Tommy Robinson isn't the first to that the UK has jailed after a secret trial. Melanie Shaw tried to expose child abuse in a Nottinghamshire kids home -- it wasn't foreigners doing the molesting, but many members of the UK's parliament. The government kidnapped her child and permanently took it away. Police from 3 forces have treated her like a terrorist and themselves broken the law. Police even constantly come by to rob her phone and money. She was tried in a case so secret the court staff had no knowledge of it. Her lawyer, like Tommy's, wasn't present. She has been held for over 2 years in Peterborough Prison. read, read
A sayanim (sing. Sayan; Hebrew: helpers, assistants) is a Jew living outside Israel who volunteers to provide assistance to Israel and/or the Israeli Mossad utilising the capacity of their own nationality to procure assistance. This assistance includes facilitating medical care, money, logistics, and even overt intelligence gathering. Estimates put the number of sayanims in the hundreds of thousand.
While not official Mossad agents and sometimes acting without explicit knowledge, they may work in the capacity of unregistered representatives of the government of Israel in their respective nations.
Generally-speaking, these non-Israeli Jewish volunteers are asked to engage in legal activities that will not bring them into trouble with the authorities, such as using Wikipedia to spread propaganda. There are exceptions, however, as for example in the case of Jonathan Pollard, the U.S. Naval intelligence employee who engaged in espionage on behalf of Israel's intelligence agencies and whose exposure by the FBI strained relations between the U.S. and Israel.
Victor Ostrovsky, a former Mossad katsa turned author, wrote extensively about activities of the sayanim, as has Gordon Thomas. According Ostrovsky and Thomas, the sayanim provide assistance of various kinds to Mossad officers operating in foreign countries. This assistance can include facilitating medical care, money, logistics, and even overt intelligence gathering. They can be Judges, Court Clerks, Expert Witnesses, Child Protective Service Workers, Assistant District Attorneys, Police Officers, or anyone with a great degree of power over people's lives, and will do anything at the behest of Mossad case officers (katsa) for the State of Israel against its enemies or those perceived to be unfavorable politically to Israeli policy. ("By Way of Deception", Victor Ostrovsky). Sayanim are supposedly not directly involved in intelligence operations, and are only paid for their expenses.
