The following video contains graphic images and language. Royce Brown was in prison at the Lewisburg federal penitentiary in central Pennsylvania. In January 2014, Brown was removed from a cell and put in four-point restraints, which chain an inmate's arms and legs to a platform. At Lewisburg, one of the toughest prisons in America, doubling up inmates in cells designed for solitary confinement can lead to violence, and for some who refuse a cellmate, they can be placed in handcuffs and chains.
