Don't expect Nick Berg's father, Michael, to help. He likely sides with the demagoguery that we've endured. He admits to antiwar involvement (reportedly ANSWER).
His son's death counters the past week's propaganda effort. No wonder he wants to put his son's death "behind him". He says he's angry that the public even knows his son was decapitated.
If a horrific act like this does not shake his dad's foundation and cause him to question his understanding of the situation, little else will.
If he's angry the public knows his son has been decapitated, sounds like his foundation HAS been shaken.
The question now is: which way will he turn?
I predict he'll stay with the enemy. His actions (being part of ANSWER, federal court procedings, stuff like that) made his son a target for investigation and delayed his return from Iraq. On some level he knows that.
The guilt must be overwhelimg. To counter it, he'll pull a Michael Moore or Scott Ritter.
