Largest US Police Departments

There are three major branches of the criminal justice system in the United States:

  • Courts – 80% of cases are civil, whereas 20% of cases are criminal
  • Corrections – supervision, treatment, and punishment of criminals
  • Law enforcement – officers that uphold the law in society

There are almost 18,000 police departments in the United States, all of which play a central role in investigating suspicious activity, arresting suspects believed to have committed crime, and prosecuting those found guilty of those crimes. Of course, law enforcement officer duties are not limited to this. Officers are also equipped with the skills necessary to:

  • act as first responders to emergency situations
  • secure threats – active and potential – to public safety
  • protect national infrastructure
  • protection of public officials

Some police departments are local, small, but well-organized with a considerable level of community involvement – such as Corvallis Police Department in Oregon – whereas other departments, such as New York City Police Department – are broader, deeper and are far more multifaceted and layered. The organizational structure among departments is therefore often very different and with it, the implementation of law enforcement itself.
