Right I should have specified the USA.

I’ll give you the long-winded “not a lawyer” answer, if you don’t like it, take it up with the fake bar association.

If you are making a living by your appearance like a celebrity, then you can sue for unauthorized use of your likeness. If you are a normal Joe Schmoe that’s not really an argument you can make.

I found this out when I was working for a university and we had a lawyer in our video production department. We used to make anyone on camera sign a waiver, the lawyer said it’s not necessary unless they were a minor, or some other circumstance that involved being mentally competent, or like aware of the video production.

But the lawyer was clear that if we filmed with a celebrity we had to get a waiver signed.

Now things are totally different if you are filming someone who is not aware of the camera in a space where you would expect privacy like a bathroom.

Anyone else in public is fair game as far as the law is concerned. While it’s creepy, you can definitely film anyone in public, I’ve heard protestors claim you can’t film their face or even young girls in public, same shit, no one has any authority to stop you from filming, the law is on your side.
