Thanks to increased funds from Obama's Justice Department (that he later regretted), there are increasing amounts of police officers in public schools—often disguised behind the benign term "school resource officers"—resulting in an even easier access point for the school-to-prison pipeline.

Indeed, analysis of National Center for Education Statistics data shows students are more likely to enter the criminal justice system if their school has a police presence—oftentimes while still enrolled in school.

That's not to mention the at least 87 Taserings of students that have happened at American public schools since September 2011.

Across the country, private police are chronically undertrained and inadequately regulated. It doesn't help that the requirements to become an armed private security guard are lax in many states. Just four states require mental health evaluations. Few conduct any kind of investigation into shootings by security guards or conduct comprehensive background checks. None meet training standards set by the industry's own trade organization.

Virginia's special police, or "Special Conservators of the Peace," are private citizens who can apply to a judge for the ability to arrest people, carry a gun, direct traffic, and otherwise present themselves as police officers. There are around 750 in the state. Inevitably, there are multiple reports of them carrying out false arrests.

Through its controversial 1033 program, the Department of Defense distributes military-grade weapons and technology to local police forces.

Among those are campus police. Records obtained by MuckRock show that the Pentagon has given thermal imaging equipment to Yale University, and passed along armored trucks to four colleges in Florida, Maryland, Texas, and Washingon. Ohio State University got a mine-resistent "ambush protected" vehicle.

Not to be outdone, the Department of Homeland Security has been training campus police officers in paramilitary-style policing since 2007.

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.
