In some circles, JFK was even more despised than DJT is today, in "certain circles".
An Excerpt from “Dallas 1963”
" John and Jackie Kennedy return to their suite at the Hotel Texas at 10 a.m. In fortyfive minutes they will leave for Dallas. Kennedy’s aide Kenny O’Donnell comes into the suite with a copy of the Dallas Morning News. The president skimmed the headlines earlier, but didn’t look through the whole paper. O’Donnell shows him the fullpage advertisement denouncing him on page 14. Kennedy reads every word, grimacing. Finished, he hands the paper over to Jackie for her inspection.
He shakes his head and says to O’Donnell: “Can you imagine a paper doing a thing like that?” JFK Wanted for Treason flyer
A flyer that circulated around Dallas prior to President Kennedy’s arrival, claiming he was wanted for treason for “Betraying the Constitution” and for giving “support and encouragement to the Communist inspired racial riots,” among other supposed violations.
Then he turns to Jackie: “Oh, you know, we’re heading into nut country today.”
Kennedy begins pacing around the hotel room. He stops in front of his wife: “You know, last night would have been a hell of a night to assassinate a President.”
She gives him a look.
“I mean it,” he continues. “There was the rain, and the night, and we were all getting jostled. Suppose a man had a pistol in a briefcase.”
He points at a wall with his finger and pretends to shoot: “Then he could have dropped the gun and the briefcase and melted away in the crowd.”
A few weeks earlier, he’d met in the White House with Jim Bishop, the author of “The Day Lincoln Was Shot.” Kennedy said his feelings about assassination were similar to Lincoln’s:
“Any man who is willing to exchange his life for mine can do so.”
Jim Garrison certainly was of the opinion the clown agency played a role:
In January 1968, Garrison subpoenaed Kerry Wendell Thornley – an acquaintance of Oswald's from their days in the military – to appear before a grand jury, questioning him about his relationship with Oswald and his knowledge of other figures Garrison believed to be connected to the assassination.[25] Thornley sought a cancellation of this subpoena on which he had to appear before the Circuit Court.[26] Garrison charged Thornley with perjury after Thornley denied that he had been in contact with Oswald in any manner since 1959. The perjury charge was eventually dropped by Garrison's successor Harry Connick Sr.
During Garrison's 1973 bribery trial, tape recordings from March 1971 revealed that Garrison considered publicly implicating former United States Air Force General and Deputy Director of the Central Intelligence Agency Charles Cabell of conspiracy in the assassination of Kennedy after learning he was the brother of Earle Cabell, the Dallas mayor in 1963.[27] Theorizing that a plot to kill the president was masterminded out of New Orleans in conjunction with the CIA with cooperation from the Dallas police department and city government, Garrison tasked his chief investigator, Pershing Gervais, of looking into the possibility that General Cabell had stayed in the city's Fontainebleau Motel at the time of the assassination.[27] The Washington Post reported that there was no evidence that Gervais ever followed through with the request and that there was no further mention of General Cabell in Garrison's investigation.[27]
US talk radio host David Mendelsohn conducted a comprehensive interview with Jim Garrison which was broadcast in 1988 by KPFA in Berkeley, California. Alongside Garrison, the program featured the voices of Lee Harvey Oswald and JFK filmmaker Oliver Stone. Garrison explains that cover stories were circulated in an attempt to blame the killing on the Cubans and the Mafia but he blames the conspiracy to kill the president firmly on the CIA who wanted to continue the Cold War.[28] "
Just seems to me with today's computer modelling, if we can model the formation of a galaxy, we should be able to calculate a bullet's trajectory based on the damage created from its impact.
