I believe Bob Lazar. The smear campaign against him is very real. Anytime I saw a Bob Lazar post on plebbit the people saying he's a fraud or a phoney would have numerous comments about him in their history. As if they were always searching for Lazar posts to trash. The majority of the people in the ufo community seem to have an angle or at the very least seem disingenuous. I never got that vibe from Bob. Now bring on the downvotes and anecdotes about MIT and him being a pimp.
