Law of the United States In the United States, the law is derived from five sources: constitutional law, statutory law, treaties, administrative regulations, and the common law (which includes case law).[17]
History of United States prison systems Incarceration as a form of criminal punishment is "a comparatively recent episode in Anglo-American jurisprudence," according to historian Adam J. Hirsch.[2] Before the nineteenth century, sentences of penal confinement were rare in the criminal courts of British North America.[3] But penal incarceration had been utilized in England as early as the reign of the Tudors, if not before.[4] When post-revolutionary prisons emerged in United States, they were, in Hirsch's words, not a "fundamental departure" from the former American colonies' intellectual past.[5] Early American prisons systems like Massachusetts' Castle Island Penitentiary, built in 1780, essentially imitated the model of the 1500s English workhouse.[5]
