Nemo, that’s simply not true. I’d love to see a cite.
And David, I wasn’t trying to imply that Posner’s explanation for the hole in the jacket, by itself, denoted a faulty use of Occam’s razor; I’m sorry if I wasn’t clear. What I meant was that no theory in which Oswald was the lone shooter has successfully explained, or usually even tried to explain, all the possible problems with that theory–including

[li]Oswald’s past intelligence connections and history in Russia[/li][li]Ruby’s intelligence connections[/li][li]the bullet mark under the overpass[/li][li]the problems with the rifle (including confusion about what type of rifle it was)[/li][li]the testimony of the doctors to initially examine Kennedy’s body (who saw the wound in the back of the head as an exit wound, not an entry wound)[/li][li]Oswald’s notoriously poor marksmanship while in the military, combined with the difficult multiple shots he had to make in a short amount of time with a faulty rifle[/li][li]the so-called “magic bullet”, found pristine after the fact[/li][li]testimony of those who saw or heard things by the grassy knoll, most of whom were not called by the Warren Commission[/li][li]the unreliability of Oswald’s wife as a witness against him[/li][li]the timing problem inherent in eyewitnesses who saw Oswald in the Depository, but several floors down from the spot where the rifle was found, only seconds after the shooting[/li][/ul]
That’s off the top of my head; I’ll try and find the book tonight. All I’m saying is that it’s bad science to shape evidence to fit your theory, rather than the other way round. And in the case of the Kennedy assassination, it’s always looked as if things which don’t fit the lone-gunman explanation–an explanation which was arrived at almost immediately following the shooting–have been discarded, rather than examine.
I’ve got no particular dog in this fight–I don’t have a pet assassination theory; I’ve got no clue who killed JFK. Hell, it could have been Oswald acting alone. But proponents of the lone gunman theory don’t ever tackle the discrepancies, preferring instead to (as Posner sometimes does) ridicule those who bring those discrepancies up.
And Occam’s razor? If there’s conflicting evidence about where the shots were fired from, how many shots there were, and how they entered the President (and there is), and if it takes sharpshooters with well-kept weapons to replicate the shots from the Depository (and even they can only do it half the time), and if there are a host of past connections that seem to lend the incident an air of complexity (and there are), and if the Commission set up to investigate the matter allows conflicting testimony in support of a single gunman while virtually ignoring all evidence to the contrary (and they did), then how is it applying Occam to posit that a historically bad shot fired multiple times in a short period with no help whatsoever before, during, or after the fact?
Call me a skeptic.
