A sniper's mind

The deadliest sniper in American history speaks to the BBC:

Brian Sain, a sniper and deputy at the sheriff's department in Texas, says many police and army snipers struggle with having killed in such an intimate way. "It's not something you can tell your wife, it's not something you can tell your pastor," says Mr Sain, a member of Spotter, an American association that supports traumatised snipers. "Only another sniper understands how that feels."

But for the US's deadliest sniper, remorse does not seem to be an issue. "It is a weird feeling," he admits. "Seeing an actual dead body... knowing that you're the one that caused it now to no longer move." But that is as far as he goes. "Every person I killed I strongly believe that they were bad," he says. "When I do go face God there is going to be lots of things I will have to account for but killing any of those people is not one of them."
