Milwaukee Police Department (Images of America: Wisconsin)

The Milwaukee Police Department was organized in 1855 with a determined chief, seven pugnacious officers, and little money. The department grew to 21 men by the start of the Civil War in 1861. Law enforcement in the city soon earned the national reputation for honesty, integrity, and fairness it has enjoyed into the 21st century. The Milwaukee Police Department was first in the country to establish a formal officer training school, police bomb disposal vehicle, and "talking squad car." Nefarious criminals handled by the department include the foiled presidential assassin John Schrank, the serial killer Jeffrey Dahmer, and characters with quaint nicknames like "Cat-eye Lil" and "Kelly the Choker."
