Take a good look at the RR workers perched atop the Triple Underpass on 11/22/63. Those guys are "Roustabouts". They do Not wear lightly colored, long sleeve pressed shirts, with a Beret dipping down over 1 eye. They're Not Charlie Bronson. And for the record, before the PC Police started bullying people around, DCM was known as "The Cuban". For a very good reason.
Yes, he was indeed referred to as the Cuban, which doesn't strike me as particularly non-PC. The fact is, Louie thought he looked like a Negro, but Louie said he really didn't pay much attention.
Here's a web page with all sorts of stuff, including graphics of DCM and Umbrella Man and even an article suggesting DCM was at both Love Field and Parkland Hospital (he is also rumored to have been in the autopsy room at Bethesda, but I have been unable to confirm this):
https://merdist.com/wp/2021/11/21/umbrella-man-and-the-cuban/In this version, DCM is "Cuban terrorist, virulent Kennedy-hater, one-time doctor, Orlando Bosch, who at the time of the assassination was in a frenzy trying to organize the removal of Fidel Castro from power in Cuba." Sure, why not?
Jack White, we are informed, has "nailed" - nailed, I tell you - Umbrella Man as "CIA operative Gordon Novel." Sure, why not?
Am I the only one who finds this stuff absolutely hysterical?
