Did all 3 branches sign off? I find that hard to believe unless SCOTUS issues classified decisions. Given Scalia’s dissent in the recent DNA case, I find it very hard to believe that he would be supportive of such a general warrant (in the historic sense of that term).
The 3rd branch is not just SCOTUS. It is the judiciary, which includes the FISA court.
The Supreme Court confirmed the circular argument that dialing your phone means (for no stated reason) that you are “assuming the risk” that they will give the information about the call to somebody, and therefore they are compelled to do just that.
The other obvious lie in the decision is that the act of dialing itself is a “voluntary” sharing of the information and not simply the action of making the call.
