60 Minutes: Season 49, Episode 25

49 - 25: Poisoned | Prisoner 760 | Poisoned Again?

Poisoned: 60 Minutes examines the unfortunate fate that stalks some of Putin's most prominent critics: unsolved shootings, suspicious suicides and poisonings.

Prisoner 760: Mohamedou Slahi gives 60 Minutes an uncensored account of the now-illegal enhanced interrogation he endured at Guantanamo Bay -- and why he says it doesn't work.

Poisoned Again?: 60 Minutes had already interviewed Putin critic Vladimir Kara-Murza when news broke that he was in the hospital again. Poisoned, he says, for speaking out against the Kremlin.
