Wait, wait, wait...
I heard the "experts" say that the surveillance was to STOP attacks...not for prosecution.
Your post was going in a whole different direction than I was thinking...NOW I have whiplash!! LOL
Re: what you posted...I will have to think on that a get back with you.
No attack was every stopped by listening. At some point, force has to be applied.
That Brooklyn Bridge guy was arrested and tried in a criminal court. No army involved. But "run it with the military" as they say, THIS IS WAR!
