Totally with you and Norseman, among others on that! But in that regard I need to express the whole idea and intent for e-DNA. It's NOT for the masses. It's for us and the scientists. And even among us there will be doubters. But the scientists will have irrefutable scientific evidence of the creature's existence. That's the point of e-DNA. The masses will decide what they will decide. I don't care about that because science will end up being the entity that will do the studies, procure the body if need be, or do a serious investigation to support the evidence.
The short, although extremely more dangerous, road is a bullet. And the risk of losing the evidence, along with one's inevitable encounter with the law, is very high. So much on the table to consider.
As far as out little plastic boxes that we deploy in the field? Yes, I have one, but I prefer the more instantaneous handheld devices that, if I'm lucky, will only alert the quarry after it's too late for it to hide.
