Important bit of context on the detainee legislation and the associated debate in Congress, from the Boston Globe:

As lawmakers prepare to debate the CIA's special interrogation program for terrorism suspects, fewer than 10 percent of the members of Congress have been told which interrogation techniques have been used in the past, and none of them know which ones would be permissible under proposed changes to the War Crimes Act.

But that doesn't stop the esteemed gentleman from Alabama: "I don't know what the CIA has been doing, nor should I know," said Senator Jeff Sessions, an Alabama Republican.

The piece points out that the Army Field Manual spells out in detail which interrogation techniques are acceptable and which are prohibited, which undermines the Administration's contention that the details of its interrogation techniques should remain classified.

It sort of fits that the same folks who let the Administration keep them constantly in the dark don't see anything wrong with keeping alleged terrorists in the dark about the evidence against them.
