DALLAS (AP) — Robert F. Kennedy Jr. is convinced that a lone gunman wasn't solely responsible for the assassination of his uncle, President John F. Kennedy, and said his father believed the Warren Commission report was a "shoddy piece of craftsmanship."

Kennedy and his sister, Rory, spoke about their family Friday night while being interviewed in front of an audience by Charlie Rose at the Winspear Opera House in Dallas. The event comes as a year of observances begins for the 50th anniversary of the president's death.

Their uncle was killed on Nov. 22, 1963, while riding in a motorcade through Dallas. Five years later, their father was assassinated in a Los Angeles hotel while celebrating his win in the California Democratic presidential primary.

Robert F. Kennedy Jr. said his father spent a year trying to come to grips with his brother's death, reading the work of Greek philosophers, Catholic scholars, Henry David Thoreau, poets and others "trying to figure out kind of the existential implications of why a just God would allow injustice to happen of the magnitude he was seeing."

He said his father thought the Warren Commission, which concluded Lee Harvey Oswald acted alone in killing the president, was a "shoddy piece of craftsmanship." He said that he, too, questioned the report.
