Lee Harvey Oswald was killed before he could tell the world why he assassinated President John F. Kennedy. Suppose he did live, that Jack Ruby was stopped over never attempted to kill him.
Would he have ever confessed?
What reason would he give?
If, based on his background as a defector to the Soviet Union and pro-Castro activist, Oswald said he killed Kennedy because of his Anti-Communism, what would be the public reaction?
This thread assumes no conspiracy, and he acted alone.
