Are the Ten Commandments the Basis For Our Laws?

People seem to accept that our laws are based on the morals of the Old Testament laid out in the Commandments, but as a proper skeptic, I decided to take a look myself. Why not go over the Commandments, said I to myself, and compare them to our actual laws, as well as the Constitution, the legal document framed by the Founding Fathers, and upon which our laws are actually based?
