Torture and national security — will the election turn on which candidate's tougher?

This year's Oscar-winning feature documentary, Taxi to the Dark Side , tells the story of an innocent Afghan taxi driver who died while being interrogated and tortured by U.S. soldiers. NOW ON PBS interviews the film's director, Alex Gibney, about torture practices of the United States in Afghanistan, Iraq and Guantanamo Bay and how the issue is playing out in the presidential race. At the intersection of human rights, civil liberties and national security, how should America respond?

NOW's Web site at www.pbs.org/now reveals where Congress, the CIA, the Bush administration and the presidential candidates all stand on the issue of torture. Also, get insight into what's going on at Guantanamo from a former detainee.
