CNN INTERNATIONAL 2008-05-16 Bobby Kennedy assassination controversy & effort to restore Sirhan's recall Anchors Sasha Herriman, Adrian Finighan in London Lawyer for Sirhan Sirhan in New York Manhattan Attorney William F. Pepper says a second gunman -- and not his client, Sirhan B. Sirhan -- shot and killed the U.S. presidential candidate, Senator Robert F. Kennedy (D-NY), in June 1968. Pepper, who has taken the case in the wake of lawyer Larry Teeter's death in 2005, says he'll try to obtain a new trial for Sirhan. William Pepper says efforts are under way to try to arrange for a restoration of Sirhan's memory of the RFK shooting (which Sirhan, since 1968, has claimed he cannot remember). Pepper's evidence of Sirhan Sirhan's wrongful conviction incorporates a number of different things including audio recording preservation of the sounds of the actual shots fired in the Bobby Kennedy shooting. Researchers Robert J. Joling and Philip Van Praag say a recently-discovered audio tape known as the Pruszynski recording shows there was a second gunman in this second Kennedy assassination. Bill Pepper says he's quite impressed with the findings of Phil Van Praag and Robert Joling.
