You're the one making the claim. If you can't mention one thing that separates him from all the other nuts and attention seekers then why should I bother to infringe on my hot-ass-nailing time to go and look into it?
Is everyone an "attention" seeker? Are all motives for going public the same?
Under great duress he, Bob, (not the Smokin' Hot one) was the first one of his kind to go public with what he knew. This was not driven by finance and fame but rather as a push-back to his former employers, and the only reason anyone knows about him now is simply because of timing and the beginning of the Art Bell show. Without Art's show the Bob Lazar story would have flickered out quite quickly and having gained nothing. For what?
Looking for motive here, and you can't tell me that there was anything to be gained back in May of 90 when he spoke in shadow on the local Vegas news.
And if you wanna step outside, we can do that too. Better have your chops up and better pack a lunch!
