It is imperative that all information on this be released.  It can not continue to remain hidden if it is shielding someone or some government.  LBJ is dead and his legacy is what it is so there can be little reason to cover for him.  There was another theory that Israel desired Kennedy gone since he had denied  them access to our nuclear secrets and they  were bound and determined to obtain nukes, at any cost.  If so, this should be uncovered and our "ally" given credit where due.  Perhaps their influence is what is holding up the release.  One thing is certain, it wasn't done at the hand of the patsy Lee Oswald.  He was a very convenient scapegoat but didn't have the marksmanship skills, nor the ability to reload and refire his old rifle in the time the incident took.  Was it the mafia?  Or??  Is the perpetrator still on the loose waiting to commit another act of vengence or is the event done?
