NICE SCARF...
It's not just "IRONY", as many here are saying. I have my suspicion about why an active dissident would be in such proximity to a car bomb.
The terrorists aim for soft targets and common folk. First because they don't have the stomach for a real fight and secondly because it helps spread terror. So I suspect she was just unlucky to be with ordinary Iraqis.
If it was not random, I'd suspect they targeted her because Code Pink having a martyr would be useful to them. It would hand Code Pink a "prize pony" to display. Everyone knows they don't give a damn about dead or wounded soldiers, that they use them as props.
I doubt she was working directly with "the resistance" because they look down on women. But who knows, if she was, it wouldn't surprise me.
