As noted in the article, the take away is that this program must be collecting a whole load of data on a heap of US citizens.
If the program was operating as it should, within the limits specified and in the spirit of the authorisation, then the agencies have nothing to worry about and the program can be re-authorised because it's doing what it's supposed to within the boundaries proscribed.
If that is the case then the response from the NSA will show that and all nothing will be in jeopardy.
If, on the other hand, these powers are being abused then an accurate report, as requested, will show that and then the powers are in jeopardy.
In other words, extraordinary powers have been given and those powers come with the responsibility to use them as directed. If you abuse that then you should expect to have the powers removed or severely limited.
To the NSA et al: if these powers are really that essential for national security, why are you risking them by abusing them? Your abuses put the American people at risk!
