The Most Pervasive JFK Conspiracy Theories

According to author and attorney Vincent Bugliosi, if a person added up all of the people accused of assassinating President John F. Kennedy in Dallas on November 22, 1963, and all of the conspiracies they were taking part in, you'd wind up with at least 42 different groups, 82 separate assassins, and 214 people playing some kind of role in the crime. But one thing is for sure: the death of John F. Kennedy rocked the nation.

Who assassinated JFK? Since the day when Lee Harvey Oswald, a former Marine, was arrested for firing three shots at the president, outside observers have felt that there was more to it. There had to be. How could the most powerful man in the world - a charming, handsome, wealthy titan - be struck dead by some ordinary loner with a rifle? It had to be a conspiracy.

JFK conspiracy theories surrounding the assassination of the President began almost immediately. They involved everything from witnesses on the grass near the motorcade to powerful businessmen to foreign powers to the usual conspiracy standbys like the Illuminati. Since then, countless books have been written, two separate commissions were formed (which came to different and disputed conclusions), and endless pontificating spouted. While conspiracy theorists continue to insist that others were involved, so far, their theories remain just that: theories.

Here are the most popular and pervasive JFK assassination conspiracy theories. Who really killed JFK? Read on to learn what some theorists think.
