Konoha Military Police Force

The Konoha Military Police Force serves as the judicial arm of the Hidden Leaf, charged with upholding the law inside the village. Though many assumed the Uchiha created it, the Second Hokage actually established the force and entrusted it to the clan as a token of goodwill between the Uchiha and the Senju.

Officially the force existed to police the village's own ranks, described as elite shinobi set to watch over fellow shinobi. Its members drew mostly from the Uchiha, since, as Itachi reasoned, only powerful ninja could bring other ninja to heel. The organization could not detain Anbu operatives without a warrant, because Anbu answered straight to the Hokage, and that gap in authority bred friction between the two bodies. Its emblem, a four-pointed star bearing the Uchiha crest, later had that crest swapped for the Leaf symbol once the clan fell.

Fugaku Uchiha stands as the last leader of the clan-run era, and until the Uchiha's eradication every commander came from their bloodline. Some members, among them Setsuna, came to view the force as a tool for sidelining the clan, a suspicion Tobi later echoed, though Tobirama insisted he had meant only to channel the Uchiha's dedication and keep their emotions in check. After the massacre, oversight passed to the Fuma clan, distant relatives of the Uchiha, with Kotaro Fuma heading the force in the anime and Kiba serving as its captain in the manga.
