That is, did Ritter consciously decide to adopt an outspoken pro-Saddam viewpoint in anticipation of his predilections becoming public, knowing that such exposure would then damage the pro-dictator crowd?
If so, that is in some sense a noble decision. It doesn't mitigate his crimes, by any means, but he definitely fell on his sword.
I think perhaps it's more likely that the Administration discovered the arrest and forced Ritter to go to the "other side" with the intention of releasing the damning information at a critical stage in the debate. It has definitely been made public at a crucial time.
"My heart's telling me to kill Saddam, or, I don't know, maybe my gut tells me that,'' he said. ''My heart's telling me to do what the Constitution says, but the gut's saying kill Saddam. And my brain has no clue which way to go here. It's just twisted. And I'm honest when I say I get up every morning and I just want to get the hell out of this."-- Scott Ritter, November 2002
