This cartoon is suggestive of the obliviousness of some of the naysayers around here…

They read the conspiracy books and get drunk on all of this history about the CIA and Operation Northwoods and Guatemala and intrigue and spying and military industrial complex and Allan Dulles. So they have to interpret the assassination through that view, through that history. It's the only way for them it makes sense. The nut with the umbrella is not a nut with an umbrella; no, he's signalling the sniper teams. Secret teams and CIA and spies and coverups and Cold War intrigue and....they can't resist it.
It's the Jim Garrison view. We can't reason with it.
