There is a crisis of trust in modern policing. At this critical time, Avon and Somerset offered unprecedented access to its ‘Professional Standards Department’, the unit that polices the police.

Over 4 years, cameras followed cases from the point of view of investigators, accused officers, victims, legal professionals and community leaders. The resulting 3 part series examines cases that range from sexual predators within the police, to how they deal with the most vulnerable members of society, to institutional racism. Ultimately, this shocking series asks, does a system where the police investigate themselves really work? 

Watch from January 29th
