So what's the difference between the NSA and the Police tasks? The Judge permission. I'm unable of imagine a NSA member thinking: "oh, come on, let's check out what this citizen -I know from nothing- is sending to this other citizen".
This is the same that happens in Guantanamo. Yes we're breaking the law -and I'm a lawyer- but we're getting tons of info. So what if the NSA discover a terrorist plan that would kill your family? If the NSA by this way of investigating -absolutly illegal- would have been able of avoid the 9/11 tragedy? Or the 3/11 in Madrid? Or the 7/11 in London?
It's all about how many rights can be waived for safety?
