political power in the hands of the unjust

Socrates once had a chance to debate a person of great political power in Athens. Socrates thought that political power in the hands of people that do not know the difference between justice and injustice is a bad thing. He brought an example of Cleon an orator that had convinced the Athenians to execute all the males of some city that had rebelled. The decree was recalled when the Athenians came to their senses and sent a ship to overtake the first ship that had the first set of orders.
