Then why no better stories? There are trail cameras and dashcams, and thousands of cameras running 24/7 in every little hamlet on this globe. Even walks in the woods catches everything on trail cameras. Last told there were over 36,000,000 trail cameras purchased in this country. They are out there snapping away morning / noon/ and night and no Bigfoots, aliens, DB Cooper, or Jimmy Hoffa SR.
Note that this topic is about Bigfoot, DB Cooper, or Jimmy Hoffa; regardless, the existence of photos and videos of UFOs is irrelevant — those have been, still are, and always will be rejected out of hand and ridiculed, by exactly the same people.
