Des Moines Police Department (Iowa)

The Des Moines Police Department is the municipal police department for the city of Des Moines, Iowa. The department is the largest law enforcement agency in the state of Iowa.

History
On January 21, 1896, the size of Des Moines increased significantly when state legislature granted the city a new charter allowing it to absorb the eight towns surrounding the city. As the size of the city increased, the need for public safety increased. In 1908 the city auditor issued an annual report of the city which stated appointed the Chief of Police. By the turn of the 19th century the police department was loosely structured and consisted of a patrol division and administration division. The patrol division consisted of patrol officers and detectives while the administration division consisted of jail staff.

The Des Moines Police Department saw a decrease in the number of public disorder arrests between 1910 and 1920, which is attributed to the fact that in 1911 patrol officers began patrolling in automobiles and were less likely to observe public disorder incidents.
