Which police department is NOT associated with the University of South Carolina?

The Charleston Police Department is not associated with the University of South Carolina because it serves the city of Charleston, which is geographically separate from the university's primary campuses located in Columbia. The USC Police Department operates specifically on campus to ensure the safety of students, faculty, and staff directly associated with the university. Similarly, the City of Columbia Police Department and the Richland County Sheriff's Department are local law enforcement agencies that have jurisdiction over the area surrounding the university and are therefore relevant to the university community. However, Charleston is a distinct municipality, and its police department's focus is on its own local issues and residents, which makes it distinct from those that support the University of South Carolina.
