The United States Penitentiary (USP) is a federal prison system that houses individuals convicted of federal crimes. These facilities are designed to provide secure confinement and rehabilitation for inmates, ensuring public safety while offering programs aimed at reducing recidivism. USPs are managed by the Federal Bureau of Prisons, which is part of the United States Department of Justice. Each penitentiary varies in security levels, ranging from low to high security, depending on the nature of the offenses committed by the inmates.
