From the director of RFK Must Die, Killing Oswald explores the mystery of how and why John F. Kennedy and Lee Harvey Oswald were assassinated in 1963, tracing Oswald's strange transformation from US Marine radar operator in Japan, monitoring U2 spy planes over Russia; to 20-year-old Marxist defector, decamping to Moscow threatening to share military secrets with the KGB; to pro-Castro activist in New Orleans and self-proclaimed patsy in Dallas.
