Inquisitorial Squad

The Inquisitorial Squad was a group of students, handpicked by Professor Umbridge while she was Headmistress in Harry Potter and the Order of the Phoenix, who were supportive of the Ministry of Magic. Their job was ostensibly to catch wrongdoers; however, as most of the Squad were Slytherins, they spent more time taking House points away from Gryffindors, Ravenclaws, and Hufflepuffs. Much of the squad, being Slytherins, had been at some point jinxed or in some other way 'punished' for their actions in one of their years of Hogwarts, or else was jinxed or 'punished' for being a member and doing such revolting acts. It was the Inquisitorial Squad that discovered Dumbledore's Army's rebellious acts.
