I think everyone is overlooking a significant threat. If we have information that is shared, we know when it is changed. The NSA has data that is not necessarily shared, so if the top people decide to "do you in", such as Obama and Romney, they have only to "edit" the data - and you have no way of proving they didn't. Meanwhile, we know the FISC will accept whatever NSA gives them as the absolute truth.
