For decades, the existence of secret U.S. government files linked to President John F. Kennedy‘s assassination has helped fuel conspiracy theories that others besides Lee Harvey Oswald were involved in his murder. Now the public is going to get a deeper look at the collection.  Today, the U.S. government is required to release the final batch of files related to Kennedy’s assassination on Nov. 22, 1963. Experts say the publication of the last trove of evidence could help allay suspicions of a conspiracy – at least for some.
