In France, public television raised the alarm a few years ago about the anonymization of voices and the blurring of faces of investigative sources. As a result, an anonymization policy has been implemented requiring that voices be replaced by an actor reading the text and that people be filmed from behind at the very least, or even replaced by an actor altogether.
More problematic are the archives of past investigations, which put people like political dissidents and witnesses against organized crime or the mafia at high risk of suffering retaliation. To mitigate this risk, tens of videos have been taken down, and efforts have been made to contact those who may be affected.
