You're confusing things. Both the NSA and the CIA can constitutionally intercept communications that cross U.S. borders. It's debatable how much oversight Congress can impose on those intercepts without encroaching on executive authority, but the basic principle of cross-border monitoring has been accepted for decades.

I deleted my post before I saw your reply. It just said "The CIA doesn't spy on American Citizens, that's what the NSA is for." My point being, why on earth would anybody be surprised that the CIA is spying on foreigners. That's the whole point of the CIA.

I deleted my original comment because this is a bottom of the page thread that I think takes away from the larger debate. But since there's a reply now, I'll add it back in.
