Never seen the footage you are talking about, but the thing that gets me when it comes to bigfoots,(or bigfeet, whatever the plural of them is) is this.
There have been people killed by deer, dogs, bears, cougar, and snakes(and more). There have been documented attacks by groundhogs, raccoons, beavers, birds, and even squirrels, but nobody gives them a second thought really.
When it comes to bigfoots, or bigfeet all of a sudden when someone sees one they are afraid and run or feel fear like it's for some reason going to hurt them.
Not one instance of a bigfoot causing anybody any harm at all, but everyone seems to be afraid of them.
Why?
I had a feral horse attack my truck once in Southeast Kentucky and I still don't run from horses and not really any fear of them.
I do need to add that I don't believe in bigfoot, so it's not a problem for me but to the people that do, why the fear?
