Prosecutors must review the evidence gathered by officers and determine whether to file formal charges against the suspect or to drop the case. These officers investigate crimes by gathering and protecting evidence, making arrests, providing testimony during court processes, and conducting follow-up investigations as needed.Īfter law enforcement officers investigate a criminal offense, it is up to the prosecution to represent the state or federal government throughout the court process. Law enforcement officers are tasked with hearing and investigating reports for crimes which happen in their jurisdiction. Each of these play a unique but critical role in criminal justice proceedings.

Most of these criminal justice systems consist of five components- law enforcement, prosecution, defense attorneys, courts, and corrections. These descriptions are taken from NCVC’s The Criminal Justice System unless otherwise noted. Other examples of jurisdictions include county, city, tribal government, or military installation (NCVC, 2008a). Since the individual in the second scenario has moved, the two states involved would be competing for jurisdiction, making it necessary to involve the Federal Bureau of Investigations (FBI) as they have national jurisdiction. The simplest way to compare these two is to think of an individual who commits multiple crimes in one state with an individual who commits one or multiple crimes in one state and then moves to another. The most common of these include state (police) and federal (FBI) jurisdictions. Contrary to popular belief, there is no one system of justice within the United States, but rather a combination of multiple smaller jurisdictions which are determined by the individual’s area of residence, type of offense, and more. It is directly involved in apprehending, prosecuting, defending, sentencing, and punishing those who are suspected of criminal offenses. The United States criminal justice system is the set of agencies and processes established by the United States government to control crime and impose penalties on those who violate laws.
