Oswald was 100% innocent he was clueless as to what happened on that day, if you have any doubts about Paine, Frazier, and Randle, then if the truth be known Oswald was not even in Irvin on the 21.11.63.
The case stinks from the very core, not one bit of concrete proof exists to allow a without doubt conviction on the poor guy. He was what he said a patsy meaning he gets blamed for everything and he was according to Milteer a local guy picked up to throw the public off.
Dallas was rampant with racist KKK memebers and they were used to set him up, plain and simple and it is the most logical scenario of this jumbled up circus played before the world in the coup to remove the POTUS.
