Karl-Heinz Kurras (born December 1, 1927 in Barten, East Prussia, died December 16, 2014 in Berlin) was a Berlin police inspector who served during the Cold War. Kurras is known primarily for fatally shooting unarmed student Benno Ohnesorg during a demonstration on June 2, 1967, outside Deutsche Oper against the state visit of Mohammad Reza Pahlavi, the last Shah of Iran. Kurras was acquitted of any wrongdoing in a series of controversial trials, due to which he became a prominent hate figure of the left-wing German student movement of the 1960s as well as the German New Left. They suspected that Kurras was under protection from many right-wing figures (many of whom had served in posts under Nazism prior to 1945) in the West German police and justice system and who were resentful towards the left-wing students. The incident is considered pivotal for the rise of left-wing terrorism in West Germany during the 1970s, culminating with the Movement 2 June and the Red Army Faction.
In 2009, it was revealed that he had also committed espionage for the East German Stasi during the 1950s and 1960s, but due to the publicity Kurras was receiving for his trials, the Stasi cut its ties to him.
Kurras approached the East German communist regime in 1955, expressing a desire to defect. He was convinced to remain in West Berlin and to work as an informant for the Stasi. As a spy he handed over confidential information from the West Berlin police to the East German authorities. He secretly became a member of East Germany's ruling Socialist Unity Party (SED) in 1964.
