About the Chicago Police Department
On January 31, 1835, the State of Illinois authorized the
Town of Chicago to establish its own police force. On August 15, Orsemus Morrison
is elected Chicago's first constable, assisted by Constables Luther Nichols and John Shrigley. The three-man police force
serves and protects a population of about 3,200. The Police Department pre-dates Chicago as a city.
Today, the Chicago Police Department is the second largest
in the United States, serving approximately 2.9 million residents within the 228 square miles that constitutes the City of
Chicago. The Chicago Police Department had, at the end of 2005, 13,323 sworn
police officers and over 2,000 civilian personnel.
The Chicago Police Department is divided into 25 police districts. Each district has between 9 and 15 police beats, with a total 281 beats throughout
the city of Chicago. Each of the 25 police districts is led by a district commander who, in addition to uniformed police officers,
has teams of undercover tactical and gang police officers at his or her disposal. The
Chicago Police Department Districts are organized into five larger organization entities called Areas. These area commanders report to the Bureau of Patrol.
In addition to the Bureau of Patrol, the Chicago Police Department
has four other bureaus: Bureau of Investigative Services; Bureau of Strategic Deployment; Bureau of Crime Strategy and Accountability;
and, the Bureau of Administrative services. Instead of a Chief of Police, the
Chicago Police Department has a Superintendent of Police; and, the Bureau commanders hold the rank of Deputy Superintendent.
