Better he breaks before trial than during or after... and leaving him intact is hardly an option. In a better world, he'd be treated humanely until execution, but we don't live in that world.I agree that's unusually excessive and cruel. Totally against anything and everything I ever signed up for 20 years ago.
If they're at all concerned about his safety, simply put him in a jacket, a rubber room, and raise the temperature a few degrees so that he won't shiver while sleeping, and give the traitor a humanitarian night's rest.
Anything else merely negatively reflects upon the integrity of the United States as a whole, while bringing into question, "Who the hell is in charge of these going-ons?" along with a side comment, "This isn't right. Ever."
He's still better off than most traitors...
