Who is this person? How does he know this? Who told him? Is he willing to go on public record clearly stating the what he knows?
Does there exist even the slightest possibility that no one is actually dead or missing, hence the lack of reporting? Then again, if the account is true, it certainly doesn't help (and seems a bit disingenuous) if he will not go public with the information.
If it happens (bigfoot attacks), I'd imagine that some factions in the .gov might want to supress the facts, sure. I doubt, though, that they could have anything approaching a 100% track record of shutting people up. If your premise is correct, then this thread demonstrates what a sub-standard job they are doing. The sticking point for me is not the claims of bigfoot attacks and the subsequent cover-ups, but the complete and utter lack of evidence of a cover-up. Zero.
The cases are not similar. Paulides cites the names of the missing along with those involved in the searches, descriptions of the circumstances surrounding the disappearances, police reports and/or the results of the investigations when available, interviews with witnesses, friends, and family members, as well as the precise locations of the incidents. No similar data sets are ever offered as corroboration in the "killer bigfoot" stories.
Also, isn't it curious that the powers-that-be allow Paulides to his publish his work if:
Bigfoot are responsible for the disappearances he documents, and There exists a government conspiracy to cover-up deaths and disappearances attributable to bigfoot?
