Nevertheless, there are many people who do believe that. And Sirhan Sirhan himself says he doesn't remember actually shooting Kennedy, so I don't think he would say that he did it for political reasons. Considering the fact that Bobby Kennedy was against the war in Vietnam, and the Weather Underground were trying to get that war ended, the likelihood that they would have any sympathy whatever with Sirhan Sirhan if they thought he was responsible for Kennedy's death seems exceedingly slim.
