In a rebuttal to those so-called "conservatives" who are unconcerned about the recent wiretapping incidents, there is a claim there is a far more wide-ranging surveillance program in place.
Rush Limbaugh has already indicated on his show that he has no problem with the information from warrantless wiretaps being used in court (which punctures one pro-wiretapping argument, that it is okay because it isn't being used as testimony in court, so it isn't covered by the fourth amendment).
If this other program involved domestic rather than half-domestic (i.e. one end in the U.S.) and foreign calls, then the other fig leaf drops.
Of course, some "conservatives" wouldn't give a damn if this were true. Andrew McCarthy has made it perfectly clear that he feels that the President has the power to take us into war (declaring war is dismissed as an unnecessary formality) and that once we are at war, the President can spy on anyone whom he chooses to designate a "potential enemy".
That is all.
