As municipal law enforcement agencies face more scrutiny, their private supplements—whether they be "special police" or campus police—are increasingly looking and acting their roles in the police industrial complex.
For instance, the University of Chicago's armed private police force, one of the largest campus police departments in the country, is notorious for using force to impose the University's "wall around Hyde Park"—the neighborhood containing much of the University's campus, student body, and faculty. Its role as an agent of the University reguates the behavior of not only those affiliated with the University but also the residents of the largely black surrounding neighborhoods.
The boundaries of its jurisdiction have extended far beyond the boundaries of campus, to a point where the core campus represents a minority of the total jurisdiction. As such, it is the primary police force for some 65,000 Chicagoans, most of whom have nothing to do with the University of Chicago.
Since the UofC is a private institution, its police force does not respond to Freedom of Information Act requests, though the area's state representative has filed legislation that would require it to.
