leadership, USP Marion was operated in permanent lockdown, serving as a model for ADX as a control unit prison. Carlson believed that the prison would hold criminals who were desperate enough to murder corrections officers or other inmates in the hopes of being sentenced to death. He argued that as draconian as these measures were, they were the only way to deal with inmates who have "absolutely no concern for human life". USP ADX Florence opened on January 10, 1995. The county already had nine prisons, but the lure of 750 to 900 permanent jobs (plus temporary jobs during the prison's construction) led residents to raise $160,000 to purchase for the new prison. Hundreds of people attended the groundbreaking for the facility, which was designed by two leading architecture firms in Colorado Springs and cost $60 million to build. Inmate population The supermax unit at USP ADX Florence houses 322 male inmates, each assigned to one of six security levels. It is designed for 490 inmates but has never been at full capacity. The facility is best known for housing inmates who have been deemed too dangerous, too high-profile, or too great a security risk for even maximum-security prisons. For example, Joseph Romano was sentenced to life in federal prison for plotting to murder the judge and federal prosecutor who helped sentence him to 15 years in prison for masterminding a coin fraud operation. While in prison, he plotted to murder an undercover officer who had taken part in the investigation. When this came to light, Romano was transferred to USP ADX Florence. The majority of current inmates, however, have been placed there because each has an extensive history in other prisons of committing violent crimes, including murder, against corrections officers and fellow inmates. These inmates are kept in administrative segregation. They are confined in a single-person cell for 23 hours a day. During their hour outside the cell, which can occur at any time of day or night, they are kept under restraint (handcuffed, shackled, or both). The hour outside of the cell is for exercise and a phone call if they have earned the privilege. Their diet is restricted to ensure that the food cannot be used to harm themselves or to create unhygienic conditions in their cell. Some cells have showers which further reduces the amount of handling of inmates that correctional officers have to perform. After
