Um, isn't the whole idea of a society having laws pretty much grounded in a sense of right and wrong?

Great Neo-neocon post on Jonathan Turley's Washington Post column about the outcome of a Utah case having to do with cohabitation in which one man has a sexual relationship and lives with multiple women.  Polygyny without the matrimony.  I think she does a great job taking on the way he sniffs at what he calls "morality laws."  As she points out, does he think such laws are imposed by some kind of outside force that swoops down and decrees behavioral parameters that are at odds with deeply rooted notions of what is and is not moral?
