In Esquire's feature "The Man Who Killed Osama bin Laden... Is Screwed," the anonymous SEAL member they interviewed speaks candidly about Metallica requesting their music not be used for interrogation.

 

From the Esquire piece:

He also insists that when it came to interrogation, repetitive questioning and leveraging fear was as aggressive as he'd go. "When we first started the war in Iraq, we were using Metallica music to soften people up before we interrogated them," the Shooter says. "Metallica got wind of this and they said, 'Hey, please don't use our music because we don't want to promote violence.' I thought, Dude, you have an album called Kill 'Em All.

"...But we stopped using their music, and then a band called Demon Hunter got in touch and said, 'We're all about promoting what you do.'"

"...They sent us CDs and patches. I wore my Demon Hunter patch on every mission. I wore it when I blasted bin Laden."
