The secret US prisons you've never heard of before | Will Potter

Investigative journalist Will Potter is the only reporter who has been inside a Communications Management Unit, or CMU, within a US prison. These units were opened secretly, and radically alter how prisoners are treated — even preventing them from hugging their children. Potter, a TED Fellow, shows us who is imprisoned here, and how the government is trying to keep them hidden. "The message was clear," he says. "Don’t talk about this place."
