As far as being caught doing anything wrong? Not really. HOWEVER, as a sign of a further intrusion into the privacy of citizens? Yeah, they get on my nerves. I really wish the right to privacy had been coded into the constitution.
These people LOVE to drag out the tired old line "If you don't have anything to hide then you have nothing to worry about.", while throwing a tantrum anytime the citizens ask for accountability or governmental transparency. You're always met with the blanket response: "No, for reasons of national security.".
