Dilawar was a young Afghan taxi driver, who was arrested by American troops with his three Afghan passengers in December 2002.

He was taken to Bagram airbase, used by US forces to collect and interrogate thousands of detainees captured in Afghanistan and Pakistan.

Five days later he was dead - tortured to death by American military police.

When American film-maker Alex Gibney read about Dilawar's story, he resolved to track down the men who'd killed the young Afghan. Were they acting alone, or on orders? If so, whose orders? What instructions had they been given when dealing with prisoners captured in the "war on terror"?

The military policemen who tortured and killed Dilawar have been punished. But their immediate commanding officer - who later served at Abu Ghraib in Iraq - has been promoted. No senior officer responsible for what went on at Bagram has been publicly reprimanded or punished for what happened there.

In "Taxi to the dark side", Alex Gibney tells Dilawar's story and asks what lessons have been learned about the use of torture by American troops.
