1. JFK Assassination
On November 22, 1963, the 35th U.S. President John F. Kennedy was assassinated, and there are countless conspiracy theories surrounding this killing. Theorists claim that more than one shooter were present there and that Lee Harvey Oswald was not solely responsible for the killing. Some believe that Oswald worked for the FBI, KGB or the Mafia, and that the murder was orchestrated because Kennedy wanted to bring an end to the Cold War and was against the Vietnam War, whereas another belief is that he was killed because he supported an invasion of Cuba. This is a case that will most certainly be debated about for centuries to come and thus takes the top position on our list.
