Lee Harvey Oswald, the guy some propaganda about the Rosenbergs "got to" while he was still young and impressionable, who may have been trained or programmed in the USSR, and whom, as Ion Pacepa says, Mr. K may have been unable to call off the job at the so-called last minute. Either that, or he just got totally PO-ed about the evil, evil,evil "Deep State" in
both the U.S. and the U.S.S.R., maybe got tired of being jerked around by
both the CIA and the KGB, and kinda decided to take matters into his own hands
(By the way, there are no bad shots in the Marine Corps.)
