Palpatine's Secret Police
this was a phrase used by many beings in the galaxy to describe the Jedi Knights, during the height of the Clone Wars. It was started after the Battle of Geonosis, when the general public learned that the Jedi had agreed to serve as military leaders in the Grand Army of the Republic. The phrase found even more widespread usage after many disgruntled Jedi left the Order of their own free will, and began to speak of their former comrades as "Palpatine's Secret Police."
