Constant surveillance is one of those societal boundaries where the line is hard to find. We all agree that public spaces are... public but if a plane can follow everywhere you go and record all of it, you start to get into weird creepy stalker territory. If that plane is controlled by the state then it is doubly creepy.

There aren't easy answers but it ultimately goes back to the 'Why do you need to hide anything if you don't do anything bad?' argument. And we already know plenty of answers to that argument.
