Curiously, that page has a poll that seems relevant:

"How concerned would you be about your own privacy if U.S. law enforcement starts using unmanned drones with high tech cameras and recording equipment? Would you be very concerned, somewhat concerned, only a little concerned, or not at all concerned?"

             Very concerned  Somewhat concerned  Only a little concerned  Not at all concerned  Unsure
  7/25-30/13 49%             20%                 15%                      14%                   2%

(Not disagreeing with your point, mind you)
