Walt, that's an excellent question. I have no idea what the answer is. Another question that might follow could be: If Hoover knew ahead of time that LHO was an assassination threat, then why was the motorcade route changed to go directly by his place of employment? I would think that just the opposite would be proper procedure.
If Hoover knew ahead of time that LHO was an assassination threat, then why was the motorcade route changed to go directly by his place of employment?There were three of Hoover's agents in the Texas Theater at the time Lee Oswald was arrested .... What were they doing there? How long had they been there?
Hoover knew the identity of the man before the Dallas Police had reached DPD headquarters with Lee Oswald in handcuffs....
It doesn't take a genius to see that Hoover was the mastermind who set Lee Oswald up ......
This is NOT to say that Hoover was a conspirator who plotted to murder JFK... But he certainly played a key role.
