If you want to cut to the chase: the Warren Commission’s conclusion wins by default: Kennedy probably- repeat, probably - was not the victim of a conspiracy. That conclusion wins not because it is definitive, but because it is less improbable than any of the conspiracy theories—all of which are even more flawed than the Warren Commission Report.
But, because the Warren Commission conclusion is less improbable than the conspiracy theories, doesn't make it a case-closer--not by far. Given the indecent haste of the commission’s work, the large amount of potentially significant information either deliberately withheld from the commission by the FBi and CIA, or not looked-for by the Commission, and the passage of a half century, the only reasonably credible certainty is that the case will never be closed.
The United States House of Representatives Select Committee on Assassinations was formed in 1976 to investigate the assassinations of John F. Kennedy and Martin Luther King, Jr. The Committee investigated until 1978 and issued its final report, and concluded that Kennedy was very likely assassinated as a result of a conspiracy.
The HSCA hearings were pretty much a joke,and actually did nothing to discredit the Warren report.The Committee found that JFK was probably killed as part of a conspiracy,but that said conspiracy was not the work of the Soviets,Castro,Anti-Castro Cubans, the Mafia,the CIA,the FBI,the Secret Service,or any other person or group.
It also says that (based on a Dictabelt recording from a Dallas Motorcycle cop's recorder that has since been thoroughly discredited),four shots were probably fired ,including at least one from the Grassy Knoll. So basically,the official conclusion is that ,yes,there was a conspiracy,but it didn't really involve anyone,and that yes,there was a fourth shot,but maybe there wasn't,we're not sure.
If anything,that dog and pony show strongly reinforced the fact that Oswald was the lone shooter.
