Interesting question. I happen to work for the University of Tennessee. The arrangement may be different for other universities/colleges in Tennessee, and other colleges/universities in other states.
In Tennessee, the University of Tennessee Campus Police is a duly constituted law enforcement agency, though its stated jurisdiction is the five constituent campuses of the University system (Knoxville, Martin, Chattanooga, Tullahoma (UT Space Institute) and Memphis (the UT Health Science Center)). UT Campus Police have complete authority on any campus of the system; if necessary, officers could be transferred from, say UTHSC in Memphis to UT Knoxville, and they would be authorized to assume their duties from the very second they set foot on the Knoxville campus.
Here in Memphis (I work for UTHSC) we really don’t have a discrete campus; where we are located is really a number of separate buildings and hospitals in downtown Memphis, so a number of public roads run through our “campus”. The UT Campus Police and the Memphis Police Department have worked out a jurisdictional agreement whereby MPD has ceded its authority over the public streets within the UT “campus” area to UT Campus Police, and MPD generally won’t enforce laws on those streets or take any other non-emergency actions unless specifically requested to by UT Campus Police.
On campuses (like Knoxville) where there is a discrete campus, the arrangement may be different. And, as I said, the arrangement may be different in other universities/cities/states.
