Yeah, he did.
If that were the case the FBI would not have gone out of its way to suppress information leading elsewhere, or provide false or deceptive info to the Warren Commission. Nor would it have changed the testimony of witnesses (according to those witnesses)and ignore those who had contrary testimony.
This was the most egregious action of the Deep State in our lifetime. And we have since been shown just how much the FBI can be trusted. Hoover had immediately declared (before an investigation) that LHO was the guy.
Every aspect of the “case” when carefully analyzed turns out to be garbage.
Just as he said he was a “patsy.”
