Every day, British police make two thousand arrests. For those involved it’s the ultimate high-stakes moment: one procedural error, and an entire investigation can be lost. In this new eight-part series, front line detectives analyse dramatic body-worn video footage and reveal why their fellow officers acted the way they did. They also share their expert insight into how those cases subsequently unfolded. Coming soon to the ‘Really’ channel, and available to stream on Discovery Plus.
