Oswald may have shot Kennedy, but there is zero chance that he acted alone. There are just waaaaaay too many errors that the Warren Commission committed to give it any sort of credibility. I believe it was anti-Castro forces within the CIA that orchestrated the hit. The House Select Committee on Assassinations also concluded it was likely a conspiracy in 1978. The best reasons (not all reasons listed) why I think it was a conspiracy: - Lack of security in Dealey Plaza (open windows, speed of car, lack of officers on the street -- all in a hostile city to Kennedy) - Location of death (kill zone was the only spot allowing good triangulation of fire -- suggesting a professional plan) - Oswald's likely involvement with intelligence agencies - Ruby's known involvement with Cuba - Deathbed confessions of many players, including E Howard Hunt - Mysterious deaths of MANY key players/potential witnesses - Pattern of gunfire and tens of eyewitness accounts of grassy knoll shots - Arlen Spector's magic bullet theory was/is just insane -- especially given how pristine the alleged 'magic bullet' was that they found on the stretcher at the hospital
