This is excellent- it will (potentially) put Congresspeople on the hook, politically, for what happens secretly and later tumbles out- hence, the Intelligence Committee members have an incentive to constructively monitor proceedings, and can't plead helplessness or ignorance quite so easily.

More broadly, this is the start of a trend I have been waiting for for a long time- the reinstatement of the post-Watergate limits on the executive branch and its array of spy agencies.

One statement here gave me a start. It was this:    

"A Sunni opposition group named Jundollah (God's Soldiers), which Iran says is part of the Islamist al Qaeda network and backed by the United States, said it was behind the mosque bombing, Saudi-owned Al Arabiya television reported last week." 

If only as a curiosity, it deserves a second look.
