Pat Kennedy (like his famous relatives) is a pretend defender of civil liberties. Like his father and grandfather he is an authoritarian. Those who continue to return these kinds of people to office surely do not wish to be free men and women.
In Plato's Republic, a "just" society is divided into three classes: Guardians (rule makers), Auxiliaries (soldiers and enforcers of the rules), and Workers (those who are forced to follow the arbitrary rules of the guardians).
Kennedy (and those like him) secretly resent civil liberties and covet (and apparently achieve) Guardian status in our society. The American Revolution was fought to prevent the creation of a class of would be "kings" yet voters seem determined to simply hand it over.
