These are sufficient sources. Leave these comments and references. Lifton is the most respected and published among critics. If you have a problem with him, then remove the text attributed to hime, but don't "throw the baby out with the bath water". Much of my edits revolve around FBI reports, Warren Commission Testimony, the Zapruder Film, etc. Greer and the US Secret Service set the stage for the assassination of JFK. You're doing a disservice to the United States of America and the world by framing him as a "driver" who was slow to react. The stabilized Zapruder Film clearly shows that he turned a second time to shoot JFK, his Warren Commission testimony is false, and the FBI report records his physical description, as standard with suspects. Clearly, Greer's role was beyond a driver. ("Constant vigilance" is attributed to him.) See Vince Palamara's work. Don't expect any "mainstream" source to claim what the Zapruder film clearly shows-Greer murdered JFK because the other shots were not fatal and time was running out. Extract what ut you don't see as substantiated, but don't revert to the "driver" BS.
