One of the most irritating issues facing Bigfoot researchers besides hoaxers and trolls, is misidentifications.
The photo below is an excellent example of what would be a misidentification. While driving down a dirt road, I seen this dark object beside the road. It has basically the outline of a female bigfoot with a sagital crest on top of the head.
I realized within seconds it was a burned out tree trunk, but took the picture to show how people would mistake it for a Bigfoot standing there.
In several cases that I have been involved in examining photos, it was clear that the person who took the picture knew what it was in the picture, but stepped back enough in hopes that no one would recognize that it was a burned out tree trunk and instead believe the claim that it was a photo of Bigfoot.
When a researcher is presented with a photo, they always need to play the Devil's Advocate and try to debunk the photo 100%, when they can't debunk the photo, then, and only then, should they say it's a "possible" Bigfoot photo. Never, ever, should they say that is is a Bigfoot photo.
