Shooting of Benno Ohnesorg

More than forty years later, in 2009, it was revealed that at the time of the events Kurras had been an informal collaborator of the East German secret police Stasi, and a long-time member of the Socialist Unity Party of Germany, the ruling East German Communist party; however, the motive behind Kurras' act remains unclear.[4][7][8] The new information was based on documents discovered in the Stasi archives.[4] Initial reports indicated that the archives contained no evidence that Kurras was acting under Stasi orders when he shot Ohnesorg.[5][9]

On the basis of the 2009 revelations about Kurras, the German prosecutor's office initiated a new investigation, in order to clarify definitively whether there was any evidence that the killing of Ohnesorg could have been ordered by authorities in East Berlin; in November 2011 that investigation was officially closed, with the determination that there was not enough evidence to justify reopening the case.[10] The prosecutor's office noted that, due to the passage of time, many participants in the trial were either no longer alive or otherwise unable to provide reliable testimony; also, documents relevant to the case were evidently among those destroyed by the East German foreign intelligence service in the interval between the fall of the Berlin Wall, in 1989, and German reunification, in 1990.[10]

Following up in January 2012, Der Spiegel magazine reported that research carried out by federal prosecutors, as well as by the magazine, found that the shooting was not in self-defense as always claimed by Kurras and that it was certainly premeditated. Newly examined film and photographic evidence also implicated fellow officers and superiors, demonstrating that the police covered up the truth in subsequent investigations and trials. Additionally, medical staff who carried out the autopsy on Ohnesorg were ordered to falsify their report. However, the Spiegel report indicated that the new information was still unlikely to be sufficient for the case to be reopened.[11]

Ohnesorg's death served as a rallying point for the left, and spurred the growth of the left-wing German student movement;[5] later, the Movement 2 June group (founded around 1971) was named for the day of his death.[4][12] Student activist Rudi Dutschke led student protest actions in the period following Ohnesorg's death.[13] Just after Ohnesorg's burial in Hanover, Dutschke, speaking at a conference held at the university there – under the rubric "The University and Democracy: Conditions and Organization of Resistance" – clashed with philosophy professor Jürgen Habermas over the future of the movement, with Dutschke advocating radical action that might include illegality and violence if necessary (though, in reality, his first proposed action was a peaceful sit-down strike); his intransigence prompted Habermas, who had urged a more moderate and pragmatic approach, famously to characterize Dutschke's ideology as amounting to "left fascism",[6] a formulation that he later retracted.[14][15] The student movement that swelled and, in part, became radicalised in the late 1960s, after Ohnesorg's death, influenced many future German politicians who were in their teens and twenties at the time.

A monument next to the Deutsche Oper Berlin, which was designed by Austrian sculptor Alfred Hrdlicka, serves as a memorial for the killing.[2] In December 2008, municipal authorities inaugurated an official memorial panel on the sidewalk in front of the house where Ohnesorg was shot.[2]

In Ohnesorg's hometown of Hanover, a bridge over the Ihme river is named after him.[1]
