Northfield Maximum-Security Penitentiary doesn't believing in using drugs on their violent prisoners. Northfield doesn't sedate their inmates. Northfield believes in old-fashioned methods where heavily-restrained inmates can writhe and struggle in straitjackets, bouncing off soft padded walls and rolling on soft padded floors. Thus locked-up and cared for by the trained, athletic young guards, the prisoners can work off their anger, they can work off their rage, and exhausted, they can contemplate what they've done to need to be permanently strapped up away from the light of day. The young Northfield guards have access to these online information charts providing details of restraints and methods that Northfield has proven to be effective, restraints that no prisoner has ever been able to free himself from.
Northfield practices methods no-longer considered acceptable treatment for prisoners. But, the violent young inmates are a danger to themselves and everyone around them. They are cared for by the young, highly-trained Northfield guards who make sure they'll never harm anyone again.
