Very good as always, but the line from Juvenal is typically translated as ‘who shall guard the guards themselves’ - and although the context is not political (it is about the attendants of the dissolute empress Messalina) - it is frequently cited in reference to the Praetorian Guard, who were intended to protect emperors but often got rid of them in return for a handsome bonus from the new guy (‘donative’ in the jargon).
