Flippancy, thy name is Bush
With regard to that interview with Bush, I actually find the answer to this question to be far more egregious than his "accountability moment" comment.
The Post: Why do you think [Osama] bin Laden has not been caught?
THE PRESIDENT: Because he's hiding.
3000 Americans died on 9/11.
Over 1300 soldiers have died in Iraq.
Over 10,000 soldiers have come home permanently scarred by the experience, and that's just counting those with physical injuries.
And this asshole has the temerity to turn a serious question like this into a joke?
