ADX

Emprunt à l'anglais. ADX stands for Administrative Maximum, referring specifically to ADX Florence — the United States Penitentiary Administrative Maximum Facility in Florence, Colorado. It is the highest-security federal prison in the United States, housing inmates considered too dangerous or disruptive for lower-security facilities. The term is used in journalism, true crime, criminal justice discourse, and US media. 'Supermax' is the more commonly understood popular term. ADX is a proper abbreviation rather than casual slang.
