Peter Taylor gives the definitive account of the hugely controversial alleged "shoot-to-kill" policy, Operation Kratos, that led to the tragic killing of a Brazilian man at Stockwell Tube station last July.
Jean Charles de Menezes
Jean Charles de Menezes was shot dead by members of the Metropolitan Police's elite CO19 firearms team.
Panorama investigates how Kratos evolved and how the operation went so dramatically wrong.
The programme endeavours to explain what really happened that day.
Featuring exclusive interviews with senior Met officers involved in the evolution and implementation of Kratos and filming of CO19's training, the programme explores the wider issues raised by Stockwell and follows the de Menezes family from Brazil to London in their quest for justice.
Panorama: Countdown to Killing was on BBC One on Wednesday 8 March 2006.
