Meaningless mayhem in Iraq on the first day of the holiest month

I don't know what to think about this. I mean, I know what I feel, but I don't know how to understand it. The news from the media is all too dry, lacking commentary or emotional probing, so I check the blogs, starting with those on the scene, and I find this at Healing Iraq. The actions of these particular terrorists seem more irrational than most, which is extreme, given that irrational is almost a defining characteristic of terrorists anyway.
