I am sure that there is a lethal sized weapon that could take one down, or a correctly placed shot. Who has the nerve and the luck to be that person? Well if we ever do harvest one that will only prove that they are real, not how or why they exist. We already know what they eat, but we can only guess at what has allowed them to remain undiscovered, or at least unofficial. The resistance to revealing such a creature is another guess, so if the government knows about them, which mostly I think they do, they choose not to tell the general public. That might be why the creature does exist, it would not be good for every yahoo to be out to bag one. The some-days are many when it comes to understanding any of this, but at least we have interest. Thanks to the late John Green and Dr. Bindernagel for their efforts, as well as Grover Krantz. One might think that such a burden on a person does take it's toll. I cannot imagine being in such a respected place and bearing that burden, one never satisfied in many lifetimes.
