Who shot JFK?

[ciphergoth]

For the purposes of this post, I don't really care who shot JFK; it's just a convenient mystery with which I can ask a question about truth.

Alice believes that Lee Harvey Oswald shot JFK. She believes that Lee Harvey Oswald was in the Texas Book Depository, aimed a loaded rifle and shot JFK, at which point his head visibly exploded as seen in the Zapruder video.

Bert disagrees; he doesn't know for sure who shot JFK, but the one thing he's sure of is that Lee Harvey Oswald was not pointing a loaded rifle out of the window of the Texas Book Depository at the President at the fateful moment.

What do I believe? As I say, I neither know nor care, but there's one thing I know for sure: one of Alice or Bert is wrong. In sufficiently weird conditions both of them might be wrong, but one of them is wrong for sure. We may never know which of them is wrong, but at least one of them is definitely wrong.

Does anyone disagree with this?

Ye-es, but I'm not so sure that "factually wrong" would necessarily be as important a wrongness to them as the phrase stated so baldly generally implies.

I devised Chris' scenario specifically as one that both Alice and Bert might be brought round to and yet remain convinced that they hadn't changed their position factually in any way that really counted. If the important thing for Alice is that Oswald was the killer, and the important thing for Bert is that Oswald wasn't in the Depository, and Chris talks to each of them very persuasively, they would probably both maintain that the other facts in their previous accounts don't really matter - they're just minor points of detail.

I probably wouldn't use the phrase 'factually wrong' to them, but I'm pretty sure that 'factually wrong' is how ciphergoth was using the phrase (and I did, really, mean 'normal conversation' with him, rather than with Alice or Bert).

Indeed - but the thing I want to stress is that they both could feel that they were right in the important aspects. In real life, I can imagine Alice telling Bert that she didn't really care about the details and mechanics of who was where, it was the important fact of Oswald's guilt that was the key thing. And Bert being happy that he'd proved his main point.

(Although, to be fair, it's more likely that Bert would at that point start to have a go at Alice about how she can possibly know that Oswald was the assassin without knowing any details of how he did it or even could have done it.)
