We cannot keep every single detail classified. I agree we need to be careful. But Bin Laden didn't find out about how we do things from the Internet or US Press. He was told this from other intelligence services. Regardless terrorist like Bin Laden will always have some data. He more than likely knew things that 89% of Americans never knew nor were told.
This is an investigation to correct our mistakes. Right now the fox is watching the hen house. I have somewhat a problem with this. Again, protect sources and methods, protect our folk in the field. However Americans still have a right to know some of the details. I do not trust government that much.
