Anotations

Scope note:

Institutions having facilities where people are legally committed as punishment for a crime or while awaiting trial. In North America, the term specifically denotes a facility run by the state or federal government for those who have been convicted of serious crimes, in contrast to a locally run facility for those awaiting trial or convicted of minor offences. Use "jails (institutions)" for facilities for offenders sentenced either for lesser crimes or relatively short terms.
