Lol of course! And every single crime must have time-stamped video proof of the alleged perp committing said crime, otherwise it's conjecture, right? No such thing as inference based on evidence. My bad.
An average, standard person would only need that stabilized .gif to decide there's 0% chance there's anyone but a person on the film. If you're any different, I don't know what to tell you.
No hard feelings, though - you're completely entitled to be as wrong as you want to be.
("you" being anyone - not "you" specifically)
Your example of video proof is accurate, but not how you mean it to be. To be valid evidence it must show not just that a crime was committed but give clear evidence of WHO committed it. To qualify as "proof" it cannot leave room for conjecture. As for your "average standard person", they would merely conclude that Bigfoot walks like a human, which has been claimed by more than one "witness" anyway. The original footage that gif is made from does clearly demonstrate that the camera operator had a bad case of the shakes. Is it fake? Neither the video or gif provide sufficient actual evidence to prove that one way or the other, which could be deliberate. Is the big hairy dude real? I'm not convinced, but it's an interesting story if nothing else.
