David Simon completely nails the bankrupt response to the Petraeus thing, and to all such scandals. A taste:

The arguments about character? That human sexuality isn’t the most compartmentalized element of our nature? That if someone will lie about sex, they’ll lie about other things? Really? No, sorry, fuck that tripe. Character has become the self-righteous rallying cry of far greater hypocrisy than any cheating husband. It’s the excuse that makes our prurient leer seem meaningful and reasoned.
