Your assertion that the NSA can't collect data about American Citizens would be great if it were true. There are pretty convincing arguments that they aren't abiding by at least the spirit of the law and that their lawyers are actively engaged in weasel-wording away the restrictions. I'm sorry but collecting the meta-data of American citizens is still collecting data (meta is a sub-class).
You've got a pretty strong opinion of the agency ... I'm guessing that you work for the PsyOps division. Or perhaps you're just a youngin' who hasn't been around the block quite enough times. And don't get me wrong - I've had a great life as a U.S. citizen. I gained my political awareness during the Reagan presidency and was at that point very proud of everything my country did - I didn't know how much was happening outside the view of the TV screen that I wouldn't be proud of - or how many other parts of our history could be questioned.
I'm certainly not advocating anything beyond having exactly this kind of discussion. It's not my fault that the NSA, CIA and U.S Government are viewed so negatively - they have the reputation that they deserve. I can understand why the rest of the world hates us but I hope we can decide to change our behavior.
