Look at it this way, they decided to become human shields which is about the stupidest thing a human can do, short of backing over yourself with your own car.
They made a big deal out of it so that everyone in the world would take notice of their actions.
Then, not only do they not have the intestinal fortitude to stick by what they believe in, but they also aren't honorable enough to do it anyway because they said they would to the world and to the iraqi people that they care so much about.
Personally, I think every single one of them that deserted the Iraqi people should be identified in a national database (like sex offenders) as deserters of human shielding.
But I guess I'll have to settle for the knowledge of their self-loathing and possibly be entertained by their addition to the darwin awards later on in their careers.
