On June 2, 1967, the West Berlin police officer Karl-Heinz Kurras shot and killed leftist demonstrator Benno Ohnesorg. When the West German police and the Springer press closed ranks around him and he was acquitted in court, it triggered the German '68 movement against what was seen as West German fascism. Recently archivists at the Birthler Agency, the government office which oversees the Stasi files, happened upon Kurras's records and revealed that he was also a high-ranking Stasi spy and member of the East German Socialist Unity Party.
