More then likely they want to monitor everybody. I wonder how those kiddie porn guys who get busted get caught...not that i do shit like that, ha ha but I just wonder how they get caught, would not surprise me if some agency is eavesdropping online, legal or illegally it might not matter to them so long as they get the bad guys.
Heck I don;'t even believe in this Butt dialing 911--you know these stories we hear how some drug dealer who scored a big load of drugs, so happens to dial 911 accidentally and the local fuzz shows up and makes a big bust.....me thinks somebody like the FBI was monitoring them and THEY called 911 from the dudes cell phone so the local police would show us and make a "legal bust"..there has been too many of those butt dial bust for me to believe it really happens. I though that long before word got out that yes, NSA is listening to all phone calls...people were shock by that but not me.
