Dave O’Brien has researched the JFK assassination since age 13 in 1965. In 1968, he formed a 'pen-pal' relationship with Dr. Malcolm Perry, the first doctor to treat JFK. He is one of few researchers ever granted access to the 'Oswald' window when it was locked and sealed to the public. Dave is joining this episode to discuss some of the contents of his book "Case Is Not Closed" about areas in the assassination that would not hold up in a court of law as to Oswald's innocence or quick conclusion.
