federal law enforcement agencies may become involved. State Most states operate statewide law enforcement agencies that provide law enforcement duties, including investigations and state patrols. They may be called state police or highway patrol (state troopers), and are normally part of the state Department of Public Safety. In addition, the Attorney General's office of each state has its own state bureau of investigation, such as in California with the California Department of Justice. The Texas Ranger Division fulfills this role in Texas, although they were founded in the period before Texas became a state. Various departments of state governments may have their own enforcement divisions, such as capitol police, campus police, state hospitals, department of corrections, water police, environmental (fish and game/wildlife) conservation officers, or game wardens (with full police powers and statewide jurisdiction). For example, in Colorado, the Department of Revenue has its own investigative branch. County Also known as parishes and boroughs, county law enforcement is provided by sheriffs' departments or offices, constables and county police. County police County police tend to exist only in metropolitan counties and have countywide jurisdiction. For places that have both county police and county sheriff, responsibilities are given to each: the county police are in charge of typical police duties such as patrol and investigations, whereas the sheriffs' department in this situation takes care of serving papers and providing security to the courts. County police tend to fall into three broad categories, full service, limited service, and restrictive service. Full service provides full police services to the entire county. Limited service provides to the unincorporated and special districts. Restricted service provide security to the county-owned parts of the county. Sheriffs' offices Sheriffs are police and have many different responsibilities. Sheriffs are elected officials where the head of police is appointed or hired in. Sheriffs are responsible for all three parts of the criminal justice system. They uphold the county jail, ensure safety within the courts, and have jurisdiction to enforce laws in the entire county. They have more responsibilities such as transporting prisoners, running crime labs, and collecting taxes. In Texas, the sheriff's office is normally the agency responsible for handling mental health calls. If the situation is dangerous, a sheriff's deputy has the power to take a person to a hospital on a mental health commitment immediately. However, if the situation is not actively dangerous, a warrant must be sought. With
