Jurisdiction[ edit ] A police officer and a police car are traditional identifiers of a locally based law enforcement agency. LEAs which have their ability to apply their powers restricted in some way are said to operate within a jurisdiction. Non executive powers jurisdictional coverage of Europol LEAs will have some form of geographic restriction on their ability to apply their powers. The LEA might be able to apply its powers within a country, for example the United States of America 's Bureau of Alcohol, Tobacco, Firearms and Explosiveswithin a division of a country, for example the Australian state Queensland Policeor across a collection of countries, for example international organizations such as Interpolor the European Union 's Europol.
They belong to different organizations from several layers of government.
While these agencies may have varying functions they are all authorized to investigate violations of the law and make arrests in criminal cases when appropriate.
The federal government employs several agencies in our community and in the state. These agencies will often work jointly with local law enforcement officers, although state law prohibits local police officers from engaging in police activity solely designed to enforce immigration law.
State law violations can be investigated by a number of agencies, including state police, county sheriffs and municipal police departments, although other specialized agencies have authorized police departments associated with their operations.
In Multnomah County, the majority of law enforcement activity is conducted by municipal police departments, a reflection of the fact that the county consists largely of incorporated cities.
The Portland Police Bureaua municipal police department is the largest police agency in the county and consequently conducts the vast majority of law enforcement activity in the county.
The city of Gresham has a municipal police department with sworn police officers and significant law enforcement responsibilities.
The Multnomah County Sheriff MCSO is a county law enforcement agency with a substantial policing function and operates investigations throughout the county and patrols unincorporated areas of the county.
The Oregon State Police is a state department under the control of the Governor of Oregon and operates throughout the state to enforce state laws. Finally, additional agencies such as the Oregon Health Sciences University and the Port of Portland have police departments employing state certified officers to conduct law enforcement operations relating to their business.
Although these agencies may have different missions and operations they all attempt to coordinate law enforcement operations as closely as the law permits. There are some instances where laws may prevent information-sharing and joint operations, such as national security and immigration, but in general all enforcement agencies work very closely with others in their operations.
This cooperation takes many forms, but joint communication systems, joint record systems, multi-agency training programs and multi-jurisdictional task forces and operations are some of the most visible types of multi-agency cooperation.Court System Structure, Function and Jurisdiction Performance Assessment Task 4 Kelly Schoepke Introduction to Criminal Justice Phil Schmidt November 6, Over the years the U.S.
court system has evolved into an intricately balanced legal process (Siegel, ).
Investigative Jurisdiction of the FBI: The FBI's investigative authority is the broadest of all federal law enforcement agencies.
Therefore, it has adopted a strategic approach which stresses long-term, complex investigations.
Coordination and cooperation with federal, state and local law enforcement officials on mutual drug enforcement efforts and enhancement of such efforts through exploitation of potential interstate and international investigations beyond local or limited federal jurisdictions and resources.
As a result, because both Australia and the United States are federations and have federal LEAs, Australia has two levels of law enforcement and the United States has multiple levels of law enforcement, Federal, Tribal, State, County, City, Town, Village, special Jurisdiction and others.
Criminal jurisdiction on tribal lands can be a confusing area of law because it can involve three different jurisdictions (tribal, federal and state) and must take into account additional factors such as the identity of the perpetrator, the identity of the victim, the specific type of crime committed and the locality of the crime.
Both police and law enforcement agencies operate at the highest level and are endowed with police roles; each may maintain a small component of the other (for example, the FBI Police). The agencies have nationwide jurisdiction for enforcement of federal law.
