Organised crime is the single biggest threat to the integrity of the police. With exclusive interviews and never-before-seen footage, Panorama has the inside story of how an organised crime syndicate arranged a hit on three police officers. Also speaking publicly for the first time are the law enforcement officials who tapped the phones of drug dealers, only to find themselves hearing corrupt police on the line. The programme reveals how Scotland Yard woke up to the extent of corruption and the extraordinary lengths that the criminals would go to in order to undermine the police’s ability to catch them.
