Why not just put less trust in video?

The courts should know that videos can be doctored, just as images can be photoshopped.

As the burden of proof lies with the accuser, it is they that would need a bullet proof argument that you did in face do what the video claims you did – and video is not alone in and of itself to establish truth.

As for the data gathering: the existence of the proposed data presents a threat for the subjects (and society) in and of itself.
