I have been walking the pro-kill/no-kill fence for a while, leaning both ways for various reasons. I have come to the conclusion that we must have a body to prove existence of the creatures, but not that it has to be a dead body. I still think that we could creatively trap or sedate one for long enough to obtain adequate documentation. While they are extremely elusive, they are not beyond being brought into captivity or sedated for a time. If we could master the art of tracking them and knowing how to locate them, then the rest would fall in place. Areas like "area x" being the exception, but might be the key to getting close enough for long enough to figure out how to trap or sedate one. If you remember the Snell Lake incidence where the creature stepped onto a bed of nails, well that might indicate that they are not always able to detect a trap, it just has to be sophisticated enough to keep the creature contained or somehow sedated. Mention of them being captured in the early history of this country shows that is possible, you just need skilled horseman, dogs, and strong rope and the skill to lasso. Problem is today we rely on our tech world and our limited outdoor skills. We need to get back to the raw skills needed to overcome the obstacles. Yes, shooting one might be easier, but you still have to remove the body, what I am suggesting is far more humane and offers greater opportunity to study an individual before it's release.
