Good info.
I totally agree that the interrogations should be recorded. It was so bad at one of the posts I was stationed at that the Battalion Commander called all the troops together and simply told them that they were idiots ever to talk to CID, and double idiots for waiving their rights.
He said, "Listen to what they're saying, They 'can and WILL' use anything you say...That's not just something they have to read. They're making you a promise."
There's something wrong that some lieutenant, probably in his 20's, is going to face 20+ years in prison because we stuck them in a hot zone, left them on their own, and then came back to 2d guess them. It is an amazing thing to me.
I share your amazement--and disgust--that these young men, who are willing to bleed and die for their country, could end up on trial.
