Even in a world where perfect, indistinguishable-from-reality deepfakes could be created instantly at the push of a button, CCTV cameras would be no less useful in criminal proceedings than they are now. "Yes your honor, I can testify that I personally pulled this footage from the camera at the corner of 15th street and King Dr." Or, even better: "Yes, your honor, I as an expert witness can confirm that this footage was signed by the secure hardware key embedded in the camera at the corner of 15th street and King Dr." There, problem solved.
