Agree that it's second-hand...and even he states this. What about the 11 hours of testimony he's provided privately to congress that includes specific names, companies, and locations? What about the first-hand witnesses that congress has heard from that back-up Grusch's claims?
I mean, there are some seemingly crazy accusations...but even if only some of them are accurate, they're worth looking in to. And if it's all false, it's still very interesting that so many trusted individuals are making such crazy claims. That is its own huge issue.
