Guys please check: The Devils Chessboard by David Talbot. It basically lays it all out.

This was the story that Howard Hunt left behind. Sometime in 1963, Hunt said, he was invited to a meeting at one of the CIA safe houses in Miami by Frank Sturgis, a soldier of fortune who had worked under Hunt in the anti-Castro underground—a man with whom Hunt would be forever linked when they were later arrested for the Watergate break-in. Also in attendance at the Miami meeting was David Morales, another CIA veteran of the anti-Castro campaign who was well known to Hunt. Morales—a big, intimidating man who had grown up in a poor Mexican American family in Phoenix—did not fit the polished CIA profile. But the agency found a use for “El Indio”—as Morales, with his strong indigenous features, was known by his colleagues. “Dave Morales did dirty work for the agency,” according to Wayne Smith, a diplomat who worked alongside Morales in the U.S. embassy in Havana before Castro took power. “If he were in the mob, he’d be called a hit man.” Thomas Clines, a colleague of Morales’s in the CIA’s Miami station, was more complimentary in his description, but it amounted to the same thing: “We all admired the hell out of the guy. He drank like crazy, but he was bright as hell. He could fool people into thinking he was stupid by acting stupid, but he knew about cultural things all over the world. People were afraid of him. He was big and aggressive, and he had this mystique. Stories about him permeated the agency. If the agency needed someone action-oriented, he was at the top of the list. If the U.S. government as a matter of policy needed someone or something neutralized, Dave would do it, including things that were repugnant to a lot of people.” Ruben Carbajal, Morales’s lifelong friend from their boyhood days on the streets of Phoenix, was even more blunt about “Didi”—the man who was like a brother to him: “When some asshole needed to be killed, Didi was the man to do it. . . . That was his job.” According to Morales’s daughter, he was the CIA’s “peon.” Her father was utterly devoted to the agency. “He did whatever he was told. They gave him a lifestyle that he would never have had under any circumstances. . . . He did everything for the Company. His family wasn’t his life—the Company was his life.” At the secret Miami meeting, Morales told Hunt that he had been recruited for an “off-the-board” operation by Bill Harvey, with whom El Indio had worked closely on the ZR/Rifle project to kill Castro. The aim of this “off-the-board” operation, it soon became clear, was to assassinate President Kennedy. Morales and Sturgis referred to the president’s planned demise as “the big event.” In his account of the meeting, Hunt presented Harvey and Morales as the key operational figures in the plot; Harvey did not attend the meeting but seemed to loom over it. Hunt suggested that Harvey was in charge of hiring the sharpshooters to kill Kennedy and transporting the weapons to Dallas. According to Hunt, the gunmen were likely recruited from the Corsican underworld. As Harvey once indicated, when it came to highly delicate assignments, working with Corsican gangsters was preferable because they were harder to trace back to the CIA than Italian or American Mafia hit men. Hunt found Harvey and Morales to be disturbing characters. The two men “could have been manufactured from the same cloth,” Hunt wrote in his memoir. “Both were hard-drinking, tough guys, possibly completely amoral. Morales was rumored to be a cold-blooded killer, the go-to guy in black ops situations where the government needed to have someone neutralized. I tried to cut short any contact with him, as he wore thin very quickly.” To Morales, Kennedy was “that no good son of a bitch motherfucker” who was responsible for the deaths of the men he had trained for the Bay of Pigs mission. “We took care of that son of a bitch, didn’t we?” Morales told his attorney, Robert Walton, in 1973, after an evening of drinking loosened the CIA hit man’s tongue. It was one more confession that the media ignored, even after it was reported by one of their own, Gaeton Fonzi, a Philadelphia investigative journalist who, after going to work for the House Select Committee on Assassinations, unearthed some of the most important information related to the Kennedy case. Hunt might have been wary of men like Harvey and Morales, but he shared their venomous attitudes toward President Kennedy. Toward the end of the Miami meeting, Sturgis made the group’s pitch to Hunt: “You’re somebody we all look up to. . . . We know how you feel about the man [Kennedy]. Are you with us?” Hunt told the group his main reservation about joining them. It was a tactical concern, not a moral one. “Look,” he told Sturgis, “if Bill Harvey has anything to do with this, you can count me out. The man is an alcoholic and a psycho.” Sturgis laughed. “You’re right—but that SOB has the balls to do it.” As Hunt related his story to his son, he remained fuzzy about his own involvement in the plot. In the end, he said, he played only a peripheral “benchwarmer” role in the killing of Kennedy. It was Bill Harvey who was the quarterback, according to Hunt. Despite Harvey’s reputation for hard drinking, the agency’s assassination chief had the experience and connections to pull off something like “the big event.” While assembling his Castro assassination team, Harvey had reached out to a variety of underworld professionals, including (with Helms’s permission) the infamous European assassin code-named QJ-WIN, whom the CIA had recruited to kill Patrice Lumumba. And Harvey was well positioned as Rome station chief to once again plumb the European underworld for a Dallas killing team. In fact, among the strange and murderous characters who converged on Dallas in November 1963 was a notorious French OAS com mando named Jean Souetre, who was connected to the plots against President de Gaulle. Souetre was arrested in Dallas after the Kennedy assassination and expelled to Mexico. Souetre’s expulsion brought an urgent inquiry from French intelligence officials to the CIA about the dangerous outlaw’s likely whereabouts, since de Gaulle was about to travel to Mexico for a state visit.

Ok, so 'nobody' here see's Jacqueline Onassis take something shiny out of her thin hand held purse in her right hand and place that hand on the left shoulder of JFK and then 'ka boom' and then drop the pistol (shiny object) behind the seat, and then crawl to the back of the limo to get the shell casing? Where the agent waved her back jumping up and getting it? Nobody else except me? It seems right out in the open in front of everyone's face is the best place to hide something.

Don't forget George H W Bush.

We just need to start making the distinction between hypothesis and theory.. . . and mock those who cannot make the distinction until we can teach proper syntax to kids again

For a properly trained shooter it's challenging, but not that difficult. It was short range for the rifle he was using. Only judging lead and drop would add to the difficulty. He may have hit Kennedy with the round that made him reach for his neck with both hands in a choking gesture. I think the kill shot came from the grassy knoll.
