The word "crime" is defined as "an act committed or omitted in violation of a law forbidding or commanding it and for which punishment is imposed upon conviction by the criminal justice system.  (Free Dictionary) To control crime, to prevent crime and to provide and maintain justice are the three main goals of the criminal justice system. "Society places the burden of maintaining justice and protecting our communities on those who work for the three main institutions of the criminal justice system are divided into 3 major parts: Law enforcement, Court and Correctional System.  (Gaines & Miller 9) To be able to understand the criminal justice system, the concept of Federalism needs to be understood first. Federalism means federal government and the states share the government powers; it is a form of government in which a written constitution provides for a division of powers between a central government and several regional governments. Federalism was a compromise that the framers of the U.S Constitution agreed on so tyranny and a too powerful centered government could not be possible. In order to be capable of handling large-scale problems they allowed appeals of federalism to establish a strong government.
