San Diego Police Department (CA) (Images of America)

The San Diego Police Department dates to 1889, when out-of-control crime forced the end of the highly ineffective city marshal's office. With violence on every corner and Tombstone's venerable Wyatt Earp running the marshals' gambling interests, change was desperately needed. But the first days of the SDPD weren't easy. Within two years of its formation, the city's economy tanked, 36,000 of the town's 40,000 citizens left, and the department's newly appointed chief refused to take the job. Still, San Diego

eventually developed into one of the nation's largest cities and most popular tourist destination--a multifaceted metropolis perched between the extremes of Los Angeles and Mexico, the Pacific Ocean and the desert. Today more than 2,000 highly trained sworn SDPD officers, 700 support staff, and more than 1,000 volunteers form one of the world's most innovative and internationally recognized police forces.
