Vietnam War, Ohnesorg's death galvanized many young Germans and became a rallying point for the West German New Left. The Berlin 2 June Movement, a militant-Anarchist group, later took its name to honor the date of Ohnesorg's death. On 2 April 1968, Gudrun Ensslin and Andreas Baader, joined by Thorwald Proll and Horst Söhnlein, set fire to two department stores in Frankfurt as a protest against the Vietnam war. They were arrested two days later. On 11 April 1968, Rudi Dutschke, a leading spokesman for protesting students, was shot in the head in an assassination attempt by the right-wing sympathizer Josef Bachmann. Although badly injured, Dutschke returned to political activism with the German Green Party before his death in a bathtub in 1979, as a consequence of his injuries. Axel Springer's populist newspaper , which had run headlines such as "Stop Dutschke now!", was accused of being the chief culprit in inciting the shooting. Meinhof commented, "If one sets a car on fire, that is a criminal offence. If one sets hundreds of cars on fire, that is political action." Formation All four of the defendants charged with arson and endangering human life were convicted, for which they were sentenced to three years in prison. In June 1969, however, they were temporarily paroled under an amnesty for political prisoners, but in November of that year, the Federal Constitutional Court () demanded that they return to custody. Only Horst Söhnlein complied with the order; the rest went underground and made their way to France, where they stayed for a time in a house owned by prominent French journalist and revolutionary Régis Debray, famous for his friendship with Che Guevara and the theory of guerrilla warfare. Eventually they made their way to Italy, where the lawyer Mahler visited them and encouraged them to return to Germany with him to form an underground guerrilla group. The Red Army Faction was formed with the intention of complementing the plethora of revolutionary and radical groups across West Germany and Europe, as a more class conscious and determined force compared with some of its contemporaries. The members and supporters were already associated with the 'Revolutionary Cells' and 2 June Movement as well as radical currents and phenomena such as the Socialist Patients' Collective, , and the Situationists. Baader was arrested again in April 1970, but on 14 May 1970 he was freed by Meinhof and others.
