Zana proved that almastys existed. Recently, it was scientifically proven that she was homo sapien.
Next week, if Norse sees a sasquatch near his barn and shoots it, he will prove that "sasquatches" exist. Afterwards, if they're unsuccessful in covering up the event and DNA analysis establishes that the sasquatch is homo sapien, Norse is headed to jail. This would be done with great sensation for the governmental purpose of preventing other such shootings.
If the DNA result comes back as a Homo Sasquatchery (or whatever), Norse still goes through the system for the exact same reason s above, but also for punishing him for dragging government kicking and screaming into the absolute nightmare of including a Homo subspecies into the governance of the world with the rest of us, which is precisely what they've been trying to avoid fir the better part (or likely over) the past century.
