This story is bigger than Watergate by orders of magnitude, if it's true.

There have been "Retired intelligence officer says he has evidence of aliens" stories floating in fringe media for decades, and all of them have turned out to be cranks. Bob Lazar has been working this beat since 1989; where's the evidence?

Maybe eventually one of these times it'll all be true, but skepticism -- extreme skepticism -- should absolutely be the default position here.
