The maximum-security prison where two convicted killers pulled off a "Shawshank Redemption"-style escape has a reputation for brutality.

A 2014 report by the Correctional Association of New York, an independent non-profit that inspects state prisons and report on conditions, found Clinton Correctional Facility is a place where there is little oversight, guards regularly beat inmates, and racial tension festers between prisoners and correction officers.

The report found that while 63 percent of inmates statewide are locked up for violent crimes, at Clinton, that figure is about 90 percent. Inmates there report among the highest rates of inmate-on-inmate fights in all state prisons, driven by gang feuds and drug disputes.

Notable past inmates include mobster Charles "Lucky" Luciano and rappers Tupac Shakur, Ol' Dirty Bastard and Shyne.
