Like many other aspects of American society, much of police uniform tradition in the United States comes from across the pond. The first modern police force was established in London in 1829, and it set the standards for all Western law enforcement agencies to come, including uniform standards.
The organizers of the British Metropolitan Police made a conscious decision about uniform color when they decided how to dress the agency's officers. One of the biggest public problems in England at the time was civil unrest. The job for quelling these riots fell to the King's Army, and the troops were none too gentle about upholding His Majesty's will. As such the Army's red coats and its "lobsterback" troops were reviled by much of England's common folk. This is why the British Police Force was dressed in blue uniforms, to distance itself from the hated army.
