Sorry. Not buying it. No body ever keeps their mouth shut about anything.
However Oswald was a devoted pinko Leninist.
After his arrest, he tried to contact some kookburger leftist attorney to represent him.
I think he WANTED a trial so he could spew his asinine beliefs and become a martyr or cause celebre like the Rosenbergs.
That's my theory anyway.
Frankly there are a boatload of things about the JFK assassination that will never make sense to me.
Still think Oswald acted alone.
