Well, I've googled and hand-searched books and can't find it. So here, from memory, is an old Calvin and Hobbes cartoon. Calvin makes some remarks to Hobbes as they ride their sled about not wanting to change. He's fine just the way he is. They hit the bottom of a gorge, hard, and Hobbes suggests that maybe this ride wasn't such a good idea. And Calvin gasps, "Careful, let's be sure not to learn anything from this, now."
Update: Courtesy of Esteemed Husband the cartoon is at this site. Still working on embedding it.
Herewith, I give you the U.S. Army's highest officer, Gen.Casey:
General Casey told me on This Week that he’s worried that diversity could become another victim of Thursday’s mass killing at Ft. Hood. The incident was not the first case of fratricide by a Muslim and when I asked how the military plans to deal with this potential problem in its ranks, Casey said, “Speculation could potentially heighten backlash against some of our Muslim soldiers and what happened at Fort Hood was a tragedy, but I believe it would be an even greater tragedy if our diversity becomes a casualty here.
An even greater tragedy if diversity becomes a casualty. If that isn't a slap in the face to the victims of this jihad attack and their families, I don't know what is.
Let's be sure not to learn anything from this, now.

Update #2: The evidence just keeps on pouring in: U.S. intel. agencies have known for months that Hasan had attempted to contact al Qaeda. In this case the information was kept isolated from those who might have done something about it because of those "walls of separation" among U.S. agencies, intended to protect Privacy, Freedom, and the American Way. Or something.
