> Doesn't this also mean that a deepfake presented as evidence of crime makes you guilty until proven innocent? It means the same thing that's always been true remains true. If a prosecutor (or one side in a civil case) presents fake evidence that is convincing to the court, the other side will have to prove the evidence to have been faked. Adding machine learning to the equation and calling the fakes "deep" doesn't change that basic reality. Consider everyone who has ever had drugs/weapons planted on them by the cops. As a society we assume most of the people claiming it happened are lying, but some of them are telling the truth and some of that subset actually manage to prove it (usually because the cops managed to record themselves doing it). If the authority figures trusted by the courts intentionally present false evidence then you are stuck not having to prove your innocence but having to prove the evidence to be false or at least untrustworthy.
