Joke: 10 Commandments on Display?

A little joke that has been making the rounds on the Internet:

The real reason that we can't have the Ten Commandments in a Courthouse is because you cannot post "Thou Shalt Not Steal," "Thou Shalt Not Commit Adultery," and "Thou Shall Not Lie" in a building full of lawyers, judges, and politicians ... it creates a hostile work environment. [Author Unknown]

I may not know who wrote it, but I do (of course) understand that the above statement was probably intended as a cute little slap against public officials and lawyers, and the ever-so-current brouhaha over displaying of the 10 Commandments. Or is it? How sad and interesting that the very people who are responsible for "legislating morality" in the United States are themselves possibly guilty of breaking the most basic of social codes. Of course, I should point out that politicians are typically only accused of impropriety -- rare is the case that is successfully made, convicting a member of Congress.
