L.H. Oswald claimed he was innocent and didn't kill J.F. Kennedy. There are various theories on what could have happened that day, but I didn't "study" all the evidence and research, so I don't know what really happened.
The ten-month investigation of the Warren Commission of 1963–1964 concluded that the President was assassinated by Lee Harvey Oswald acting alone and that Jack Ruby acted alone when he killed Oswald before he could stand trial. These conclusions were initially supported by the American public; however, polls conducted from 1966 to 2004 found that as many as 80 percent of Americans have suspected that there was a plot or cover-up.
Is the Warren Commission conclusion that Oswald killed Kennedy supported by factual evidence, or is there reasonable space for some doubt and/or alternative theories?
