Which of the following is NOT a method for providing police departments to a municipality?

Purchasing private security services is not a method for providing police departments to a municipality because police departments are typically essential public services that are funded and regulated by governmental entities. Police departments serve the public interest by enforcing laws, maintaining public order, and providing community safety, which are responsibilities that only government entities can effectively perform. In contrast, private security services operate primarily for profit and do not have the same powers as law enforcement agencies, such as making arrests or enforcing the law.

The other methods listed involve different ways a municipality can establish or share law enforcement resources. Creating their own department allows a municipality to establish its own police force tailored to its specific needs. A joint department with another municipality enables shared resources and personnel, fostering collaboration to enhance public safety. Contracting services to another agency allows a municipality to access law enforcement resources without the full costs of maintaining a separate department, facilitating a more flexible approach to policing needs.
