History of South America

Which country had the greatest impact on American policing?

The correct answer is: England.

The modern police system in the United States was largely influenced by the policing system in England. The first police departments in the United States were established in the early 19th century, and they were modeled after the London Metropolitan Police, which had been founded in 1829. The London Metropolitan Police was seen as a model of efficiency and effectiveness, and its methods were widely adopted by police departments in the United States.
