This assumes good trackers are available not just within bigfootery but also for each particular alleged bigfoot track case you wish to bring forward as non-hoaxed. Given the standards of bigfootery's usual practices and investigators' skills...
Absolutely agree there, but those kinds of contacts can be cultivated. If I thought the trackway was good enough I would certainly make every effort to find one. But it's not just that, if police investigators can gather forensic evidence why can this not be a learned skill for the serious bigfoot hunter? You would think they would make learning good investigative technique a priority since they scream and holler about science not accepting what they find as evidence.
And there's another problem- possible evidence for forgery (say, knee marks besides each print) could be discounted or "explained" by the hoaxer as being the result of his/hers "investigation" of the tracks by the time it was found.
A bigfoot hunter who was serious about establishing credibility for the find would know better than to do that, or they should.
Do not forget that "hoax" is not the only explanation. Mistakes also happen (example: overstepping bear tracks).
This is true, but bear tracks are usually closer together than the ones I would think had possibility.
