Tam had this the other day, and today ran across this:
The Office of Inspector General is the law enforcement arm of the U.S. Department of Education and is responsible for the detection of waste, fraud, abuse, and other criminal activity involving Federal education funds, programs, and operations. As such, OIG operates with full statutory law enforcement authority, which includes conducting search warrants, making arrests, and carrying firearms.
Kind of like Tam, one of my first questions is "Why? Why does the OIG of the DOE need raid teams? There's no EffinBI or US Marshall's office around? No local PD or SO who can serve a warrant?" Along with the concerns of "How the hell much of our money is DOE spending so they can have their own personal ninja force?" Body armor and uniforms and sidearms and shotguns and ammo(do they have subguns, too? AR or M-16 rifles?) adds up to a fairly big chunk of change, at least when it's not other peoples money.
