But even if the warrant process is corrected, they do still have to collect the data on everyone all the time, right? I mean, it wouldn't do any good to say, "We're pretty sure the suspect called the murder victim just before he died, so let's start collecting data on his phone calls now..." They've always collected the same information (Caller ID, location of the phone call, etc.) on every call made from a landline, right?
