school resource officer
n.— «Surely, you are aware of what is euphemistically referred to as a “school resource officer.” That moniker has a nice, vanilla ring to it. But it doesn’t really get to the primary heart of the matter. A school resource officer is nothing more than an alias for a campus cop. For some time, certain public schools here in the suburbs have had full-time police officers assigned to them.» —“Campus cop” by John Horgan Inside Bay Area: San Mateo County Times (California) July 15, 2007.
