David Simon, creator of The Wire, breaks it down:

Hypocrisy will never go out of style in American journalism or American life. But sitting there and watching the rewrite and sports desk mobilize to surround the sexual wanderings of a sportscaster, I remember making a decision: Enough. This is just sex. This is nothing more than the odd, notable penis or the odd, notable vagina staggering off the marked path and rubbing against the wrong tree. This is just people.

David keeps responding in the commens, where I found this gem of a story about Churchill and the World Trade Center tragedy.

Even better is this Tumblr of David Petraeus Affair Photos.

My two cents – if you are searching for any way to react to this that isn’t based around gossip, look for the best of human emotions.
Look to bind yourselves to those in trouble, exercise your empathy and compassion.
