Now that this technology is accessible to anyone with a PC + respectable GPU, the question of "guilty" or innocent is going to become irrelevant - people can just say "deepfaked - it wasn't me" when confronted with video evidence of them carrying out any activity they would rather keep secret.
This was somewhat investigated in the classic 1980s cinematic masterpiece The Running Man where a future was predicted when faces can me mapped in real time onto actors' bodies.
Granted, they also predicted we'll all be driving Ford Tauruses and have big hair in the future, but close enough.
