This is not new. The law was passed in 2006 by Bush, it's just a continuation. The difference now is that because phone companies are not keeping the data for longer than a few years and the government want it kept for longer, so basically they are going to store it. If you watched Question Time about 3 weeks ago you'd have see that the same argument is taking place here. The British government already have a law that states they can, under a warrant, access phone records just to tell them who was called, where and the duration...not the content, they are debating a new law that enables the data to be kept because the phone companies won't keep it longer than a few years.
