So why no photographs. Most hikers carry cameras.
Indeed, my walking-stick for hiking is designed to be that (including a compass on the top knob) as well as a monopod for my rather expensive DSLR and lens (the knob comes off to reveal a standard screw mount). The point being that I'm rarely out hiking without my camera,
specifically to photograph wildlife. And I've seen and photographed (and been chased by) lots of wildlife. It's like UFO photos. They're always blurry, indistinct, and require lots of interpretation, which leads to the obvious conclusion that photos of mysterious phenomena
have to be the ones that are too fuzzy to be defensibly identifiable as anything else. That's the only way it works. You have to be able to say, "Well, the evidence is too nebulous to prove it's a prosaic this-or-that, so it opens the door to my pet mystery."
As to the lawsuit, I just don't see a lot of merit. The state's obligation to warn people of dangerous wildlife would seem necessarily in proportion to the evidence of actual danger. Wildlife
per se is not dangerous to humans; it varies greatly by species and circumstance. Yes, there are a few eyewitness-only accounts and photographs purporting to be this allegedly dangerous creature Bigfoot, but that's not evidence that's congruent in amount and confidence with the evidence establishing the existence and threat of other animals for which warnings seem appropriate. Given that any warning of danger -- valid or not -- has a chilling effect on free enjoyment of open public spaces, the responsible agency must have some discretion over what warnings to give. And where such discretion exists, it must be free to evaluate the threat based on evidence. There is a general obligation not to alarm people unnecessarily, whether it's of incoming missiles or big hairy mythical beasts. We require those who wield power under color of government to be able to articulate a rational basis for their actions and to exercise ordinary good judgment.
More importantly, it's unclear to me to what extent the state has an obligation to act in an advisory role. We recognize the obligation to conserve wild areas, but that's generally to conserve them from the effects of people, and so the state regulates people's activity so as to protect the wildlife, not the other way around. Paradoxically the state assumes an obligation to protect humans from dangerous wildlife that strays into developed areas. But it seems the state's obligation to protect people when they stray into wildlife areas is simply to advise them that a hazard is known to exist and thereafter to leave it up to people to behave in a way that to them seems appropriate. The state tells people that bears have been observed in some area, and you venture into that area at your own risk. I just fail to see how any of the Bigfoot evidence, taken in whole, rises to a level of scientific consensus that would compel a point of public policy.
