Made up stories can have elements of truth. But part truth is still not the truth.
My hotel receipt or speeding camera picture in my rental car is convincing I was in Chicago on some date and time. It doesn't mean I saw Elvis alive while I was there if I made such a claim.
People tell untruths sometimes innocently and sometimes for some other motivation.
The problem comes for someone who NEED that person or needs to believe them. It's just like how Greg Long needs Heironimus so he overlooks the changing suit, stories, timelines and so on. They can't walk away when these witness' stories don't add up. They should, but they don't.
In this case of the Bob Lezar thing, some NEED him. In the event the storyteller is exposed by massive holes in their story, those who need him will say, "Wow, the government was SO powerful they convinced him to lie for them!" For them, that government can even somehow remove him for yearbooks.
I wish this didn't have to spin into a UFO forum.
Just so you know, Mike Farrell's UFO show in the 1980's tells me Aliens like ice cream; especially strawberry. Got to be true, right
