And those 5000 reports aren't even the beginning of the testimony. There are many reports I can think of that aren't in, for example, the SSR, BFRO, Green, or any other database. An example of that are the two direct experiences mentioned by Bobbie Short of Lyle Laverty before his involvement in the PG film event (an individual sighting near Hyampom, CA, and a nest find in the Scorpion Creek/Lonesome Ridge area, which is immediately adjacent to the PG film site). One can find no details of those two events. Is that because Laverty wisely chose to keep his experiences (as an official, on-duty USFS employee) confidential? Was he ordered to do so?
The aboriginal experiences are another poorly recorded field of reports, and the quite literally go back at least 15,000 years in North America, and likely double that span of time. Bill Nelson reports several in his anthropology study of the Koyukon aboriginal group in his book "Make Prayers to the Raven", which is not a "Bigfoot book", but a study of the Koyukon peoples and their relationship with the natural world.
Do people lie? Do they make up stories? Do they embellish rel events? Yes, yes, and yes, but the lawyeresque reasoning that justifies complete disregard for human testimony with regard to sasquatchery is beyond foolish; it's denialism. Human testimony can result in conviction of a capital crine, and has done so throughout human history. It is evidence, not proof, plain and simple.
