What is most interesting about this, and the author IMO intentionally left it out, is this question; Did the feds in past instances have a warrant to obtain this tracking information? Is the current administration seeking to avoid the warrant requirement through assuming that we have no right to privacy? It appears this is the actual intent of this entire argument, and would not surprise me one bit if this is the current administration's push.

here is the more interesting thing.
Most drug dealers use pre-paid cell phones because they know that police can track them with their cells. Get warrants for their calls etc.

So the vast majority do use pre-paid where no name is required. Terrorists do the same thing.
