I wouldn't hunt Squatch... they travel in packs and are highly intelligent. Shooting one is inviting a boulder in the face...
The film argument is ridiculous... there's also no film footage of cougars/mountain lions in the wild... "But Luke, I saw this documentary about wild mountain lions and..." No you didn't, nature documentaires are shot in nature preserves where the animals are already habituated to humans and fed twice a day. The sparse video evidence for Sasquatch is far superior to that for say, the Bili Ape... a 6' 300 lb giant chimp that lives in the Congo, or the Giant Squid both of which are recognised as a real animal by scientists.
Squatch are nocturnal, they can see (or seem to be able to see) infra-red illumination, hence they won't be caught on night-vision cameras or trail cams.
