Heck, even real world cops make tons of mistakes or arrest people just to fill arrested bodies quotas and they do have judges to check upon them, at least in theory.
Or, most dangerously, because that person is outspoken politically dangerous person, not a terrorists and not planning anything, but did actually met with some terrorist twice. Say, muslim active in politics just about to do something uncomfortable for administration.
