There is no PROOF of this. Assertion, sure. Logic, sure. But proof, _absolutely_ false. I assume that certain regional / local offices probably have unofficial knowledge of bigfoot. That the knowledge rises far enough in the hierarchy for there to be an official policy, thus THE AGENCY hides anything at all from us remains unproven, and for certain "THE GOVERNMENT", meaning **all agencies** together, not just one, is hiding bigfoot from us, is patently ridiculous.
Back to another false premise you assert. If there were reported sightings, of course I'd go and my kid would come along willingly. Unexplained kidnappings is an entirely different thing. I'd go. Would not take my kid. The notion that there's any connection is just that, and is without proof.
Uh .. do you know what proof means? Because either way, you're misusing the word.
