done for....(informal)...doomed to death or destruction
Perhaps then you meant to say "did it in for him" or similar?
So you do take a one liner anonymous source on the net as gospel, and then believe another Bob Lazar story. Yet the evil Government really stuffed up, didn't they? The only information that seems to exist is that which is the inflammatory part that allegedly had him locked up.
How can you seriously consider that the Government erased the man from record, but left the reason that they erased him from the record still standing? How does that make sense?
If he ever existed at all, it is just as possible the identity is made up. Seems rather suspect to me that the only record is a dubious alien claim left on the Internet, don't you think?
