Just in case the kids decide to plant mines
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.
