It's only a mystery if you accept the information presented by the DPD and the FBI as factual information.
Most things are a mystery if you eliminate consideration of the evidence. Do you still believe those red rings were a signal to LBJ? That one always gives me a good laugh.
If your research is based on Lee Oswald's aware and knowing involvement in the murder of President Kennedy, then you're never going to find the truth behind the assassination.
Mytton, Smith and the other lynchers always point to the exposure that Oswald had to the press [Like the cops weren't twisting his arm or anything] --Oswald would have told the world the truth about the hit that went down-- He had his chance they continue to claim. An assumption that Oswald knew anything at all.... Like a patsy is supposed to know anything at all.
Simpletons laugh at that which seems impossible to them.... There would be no magicians if there were no suckers that they could trick..... I'm happy to see that you admit that you're one of the simple suckers.....
Oswald wanted historical credit not legal responsibility for his act.
