If someone is filming you without permission, asking you sexual and personal questions, and you rip their glasses from their face/snatch their mobile, and throw it down on the ground hard....that should be legal.
If you are not famous and are the predominant focus of a video or become the predominant focus, and offer no consent to filming, then you should have the right to have that video removed from public and private viewing. Where not possible, any financial rewards the video has made (including sponsorship) will go to the person(s) in the video and the video deplatormed as soon as possible.
I see it being extremely problematic to police and there are a myriad of issues with what I propose but the general theme should he adhered to. If you don't want to be on a video, you shouldn't have to be and it shouldn't be you who actively has to change what they are doing to prevent that.
Lastly, i apologise for the long winded rant.
