The Tucson Police Department was founded on April 22, 1871. The city was one square mile in size and had a population of 3,20 ... 0 people. By 1921 the department grew from a single marshal to 33 commissioned officers. During this time officers worked 12-hour shifts with an annual salary of $1,800. They were also required to provide their own uniform, badge, gun, ammunition, and they had to be married. Today, the Tucson Police Department has a chief of police and a four-bureau system. The department has over 830 sworn officers and more than 290 non-sworn employees. We serve a community of over 520,000 citizens and cover more than 200 square miles.
