Benefit concerts make for strange bedfellows. A few hours into Amnesty International's nearly endless show at Brooklyn's Barclays Center last night, a tall man with silver hair named Kerry Max Cook walked onto the stage to talk about the death penalty. Cook served 22 years on death row in Texas after being wrongfully convicted for the rape and murder of a 21-year-old woman named Linda Jo Edwards; he was released in 1997. During his time in prison the state of Texas executed 144 people. Cook, a prominent anti-death penalty advocate, told his story—on the one hand the obscene horrors of death row, on the other his small measure of good fortune in being able to speak for the executed—smoothly and without the aid of the teleprompter that earlier had tripped up celebrities like Bridget Moynahan, who wore a fedora.
