The mob did it. Or the CIA. Or Fidel Castro. Or Lyndon Johnson. Or the Soviets.
Half a century has passed since the assassination of President John F. Kennedy — one of the greatest crimes of the 20th century and the most abundant wellspring for conspiracy theorists in the history of the United States.
Polls consistently show that a clear majority of Americans believe that Lee Harvey Oswald did not act alone, and perhaps did not act at all, in the murder of the 35th president on a Dallas street on Nov. 22, 1963.
That's many more than those who believe the discredited theories that the Sept. 11 attacks were an inside job and that President Barack Obama was born outside the country and faked his birth certificate.
What are is your take on this? Do you believe there was a conspiracy? Should the assasination-related FBI files be released to the public?
