Overview of the Police Department

The police department in the US was formed in 1838 when the private businessmen demanded a system from the regime in which the public department will give protection to their goods. Gradually the system developed, and by the end of the 1800s, there was public policy in almost all the main cities of The States. Meanwhile, the private security system also emerged. This emergence gave rise to diversity in the policing department of The United States. Multiple policing agencies patrol around a single city with overlapping responsibilities.

Today, there are almost 18,000 police departments in The United States, and their central aim is to provide protection to the citizens. These agencies enforce the law, investigate suspicious activities, maintain law and order, arrest the suspects accused of committing a crime and prosecute those where the bar of evidence has been reached. The police department is a part of a bigger criminal justice system that consists of prosecutors, courts, juvenile justice systems, and correctional agencies such as prisons and probation and parole departments.
