''The Mauritanian' details prisoner abuse at Guantanamo Bay

The military prison at Guantanamo Bay, Cuba, took its first 20 detainees in 2002. Despite various calls to shutter it, it still stands almost twenty years later. A new movie now tells the story of Mohamedou Slahi, who spent 14 years within its walls, suffering abuse, even though he was never charged. Amna Nawaz takes a look at "The Mauritanian" for our arts and culture series, CANVAS.
