Historical context
Punishment was the central criminal law philosophy in English common law. A conclusive presumption that children under seven could not form criminal intent eliminated the youngest from the criminal justice system. Children between the ages of seven and fourteen were presumed incompetent to form the requisite criminal intent; the prosecutor, however, could rebut that presumption by demonstrating that the child knew the difference between right and wrong. Children over age fourteen were presumed to have the capacity to form criminal intent. There were no special courts for children, and they were treated as adult criminals. Minors were arrested, held in custody, and tried and sentenced by a court that had discretion to order the child imprisoned in the same jail as adult criminals. Although children received the same punishment as adults, they were not provided with many of the due process protections accorded adult criminals. For instance, minors did not have a right to "bail, indictment by grand jury, [and] right to a public trial."
Although the early American colonies adopted the English common laws regarding child criminals, from 1825 until 1899 several reform movements initiated significant changes both in philosophy and in treatment of juvenile delinquents. Quaker reformers spurred the New York Legislature in 1824 to pass legislation creating a House of Refuge, which separated poor children and juvenile delinquents from adult criminals. The goal of the House of Refuge movement was both to prevent predelinquents from becoming criminals and to reform those who had already committed crimes. The judge had discretion to determine which juvenile delinquents might properly benefit from the House of Refuge; child criminals unlikely to reform were maintained in adult prisons.
Juvenile justice attitudes change from time to time, from reformers to protect the rights of youths, to moral panics caused by increased criminality, prompting
