Works well doesn't it? 9-11 and the london and the edinburgh bombers all coordinated via mobile and these automatic systems did a sterling job in intercepting them.

No system can listen to the billions of calls and texts in real time and do anything meaningful with it. If 'they' are listening to you 'they' already had a damn good reason to.

having worked on 'sensitive' gov projects I really have no fears at all about what they are doing, the old phrase of p**s up in a brewery springs to mind.
