As I said, hints and allegations but after 52+ years, no, there’d be some kind of substantive evidence of some kind of fairly convincing nature. I mean even the dark Nixon conspiracy was uncovered even at the threat of death within a few years while Nixon was still in office.

There was a special a few years back explaining the second shooter from behind a small fence / grassy knoll. If just questions that our government is not truthful to the American people. (Which. opens all sorts of possibilities)
Frankly, I don't care who shot JFK; I'm sorry that he was made into something he NEVER was, by Jackie and those who helped her do this.
