The NSA is currently collecting call data for ALL of Verizon network's cell phone calls. This bulk collection of cell data should not be allowed. It is a massive violation of citizens' privacy and rights. This is very different from a warrant for specific suspected criminals with evidence to back up the warrant. This mass collection of data includes all phone models, and phone numbers called from/dialed.
In addition, the FBI has been issuing "security letters" to corporations like Google requesting massive amounts of data on American citizens, and in this case, no warrants are involved. The FBI requests complete silence. The companies are not even supposed to mention these letters. Google went to court, and it was ruled unconstitutional, but they were told to do it still.
Make. It. Stop.
