Definition of Illinois state police

The Illinois State Police (ISP) is the state police force of Illinois. Twenty-two other U.S. states also use the term "State Police." In this case state police are general-power law enforcement officers with statewide jurisdiction, who conduct patrols and respond to calls for service and perform other duties. Officially created in 1922, the Illinois State Police have over 3,000 personnel and 21 districts. The main facilities of the Illinois State Police Academy, which was constructed in 1968, are located in Springfield. Prior to 1968, training was conducted at the Illinois State Fairgrounds. ISP also maintains the Illinois sex offender registry[1] and administers the state's AMBER Alert program.[2] The Illinois State Police is also responsible for driving and physically protecting the Governor of Illinois.
