I don't buy it. The FBI could simply deny whatever this alleged guy said. If they could deny Waco and however many witnesses who claimed to see TWA 800 shot down over the LI sound, they could deny whatever this guy would say. Once arrested, he's discredited, and the judge would never let him present whatever dirt he has, and moreover they could probably find a judge who'd let them hold this guy more or less incommunicado. He'd be much more dangerous to them at large. If they haven't arrested someone, I suspect its because they haven't got a case, and if they're focussed on some guy from their own weapons lab, they may still be barking up the wrong tree entirely. This sounds like this lady's tin hat view to me.

Once a scientist working in a US government lab is arrested, the "dirt", as you say, is already out, i.e., the US has been working on weaponized anthrax which is a treaty violation.

Bingo.
