Well goodness - isn't this a bit much? Certainly a lot more intrusive than an NSA supercomputer sifting through millions of comm channels looking for words like "bomb", "nuke", "missile", etc. Why should people be concerned that NSA is monitoring all comm channels that have a foreign origination or destination? It have been going on since the cold war - get used to it. They are not "listening to your conversation" or "reading your e-mail", UNLESS you are contacting the bad guys directly. Then you might have cause for concern and maybe you should get a ACLU lawyer and sue the Government for your civil liberties. Please do so, that way we know who the enemy is - come forward.
The NSA does indeed scan all comms. Try saying "bomb" and other type things and say what you are going to "bomb" and see if that creates any action from the police.
