Clearly peoples ability to comprehend suspensions and how the government works is at an all time low.
The only department that I am aware of that has forbidden its use is the DoW.
If the NSA, or any other federal or state agency wants to use it, they certainly can as long as the information or data does not cross into the DoW's domain.
As far as I know, there is no blanket federal ban. If that's wrong, please post the directive, not some news article, the Executive Order.
From where I sit, this is a nosensical article written by someone who hasn't got a clue how the federal government works.
