CNN.com coverage of Sheehan's "resignation" from the anti-war movement here.

For upwards of an entire year after her son's death, I took Sheehan's comments as the hallmark of a woman unable to handle her son's death, desperately in need of a great deal of therapy and/or medication. Somewhere around year two, I came to the conclusion that it was about time for her to stop trying to make political hay out of her tragedy (which is far different from simply opposing the war; tons of reasonable people oppose the war - almost none of them do not try to make a spectacle out of a casualty therein). Thankfully, blissfully, she has realized that her shrill cries fell upon collectively deaf ears, and has returned to glorious anonymity.
