Quis custodiet ipsos custodes? is Latin for 'Who guards the guardians?'
'The guardian class is to protect the city. "Who will guard the guardians?" or, "Who will protect us against the protectors?" Plato's answer to this is that they will guard themselves against themselves.'
Cheshire County Council as Highway Authority should protect the county from others building unsafe roads. My question to them is 'why are they not protecting themselves against themselves?'
