Missing context: this was a civil trial, not a criminal one, which means there doesn’t have to be evidence beyond a shadow of a doubt and the verdict doesn’t have to be unanimous from the jury. If marginally more evidence supports the plaintiff, they win the case.

Which isn’t to say any of the conclusions the jury reached are necessarily incorrect, just that a civil trial doesn’t have the same level of required evidence, and it doesn’t make a guilty/not guilty determination, just one of liability.

Also potentially relevant is that Jowers’ sister claimed he lied about it to make money off the media attention, and that she backed him up so that she could pay off back owed taxes.

Trump declassifying the files about the assassination earlier this year also doesn’t scream to me that the government definitely did it.
