Trusty system (prison)
The "trusty system" (sometimes incorrectly called "trustee system") was a penitentiary system of discipline and security enforced in parts of the United States until the 1980s, in which designated inmates were given various privileges, abilities, and responsibilities not available to all inmates. It was made compulsory under Mississippi state law but was used in other states as well, such as Arkansas, Alabama, Louisiana, New York and Texas.
