Second, try as they might, NO ONE has been able to produce the sound of a fourth shot (let alone other shots) on the dictaphone recording. I have listened to it. There are clear differences in the motorcycle backfire and the shots (again, see #1).
Third, I think there is a huge difference between admitting (which Posner does NOT do) that there are unanswered questions raised by David Lifton and perhaps by Howard Donahue and concluding that there was another/were other gunman or gunmen. I don't see the two as mutually exclusive. For example, Lifton claims that the body appeared to have undergone a "pre-autopsy," and he establishes without question (I think) that the body arrived at the back of Bethesda, in a black ambulance, unloading a grey shipping casket with JFK inside. If true, that in no way means LBJ "did it." Rather, it means that LBJ, terrified that the Russkies may have killed JFK, wanted to know the "skinny" before the "official" word leaked out so he would be prepared to deal with a potential nuke war if necessary.
Another thing to consider: Bobby Kennedy, not J. Edgar Hoover, was the most powerful law enforcement person on earth. Whatever happened, his actions must be accounted for. Why didn't he order a full-scale investigation? There are several potential explanations. One is that he KNEW what JFK was up to, and didn't want all those "skeletons" revealed, particularly the Cuban stuff and the bimbos. Another, more intriguing alternative, is that Donahue is right: that Lee Harvey Oswald fired two shots, hitting JFK once and severing his spine, but that the third shot, the head shot, came from an AR-15 directly behind JFK . . . in the Secret Service trail car (photos validate such a weapon directly behind JFK at the time of the shooting, in the hands of agent George Hickey). Donahue argues that Hickey picked up the rifle, began to turn as he flipped the safety off, and slipped, discharging the weapon in JFKs direction and hitting him.
Seems far-fetched, but again, think of Bobby: aside from my first explanation, this is the ONLY other explanation as to why he would not have exhausted all resources looking for the "killer." He knew who the killers were---Oswald and the accidental shooter, an SS agent. What would have been the value in allowing THAT to come out into the public? So pin it all on Oswald, who was guilty anyway, and seal it up.
The point is, there are a lot of explanations that tie up the loose ends without getting into looney tinfoil hat conspiracy theories.
Well put. Now all that needs doing is to convince the 'lone gunmen' fanatics of that fact.
(psssstttt LBJ did it) ;0)
The military industrial complex took him out, no question. He was going to splinter the CIA, sever the ties that the Federal reserve had with their very evil scheme since 1913....and he was going to pull out 1,000 American troops from Vietnam by 1965, but; obviously wasn’t able to put it into effect. Then, the one of the most idiotic and evil presidents we had, several more to follow, LBJ reversed this plan and sent more to Vietnam as they had planned all along.
