But police (well, anyone, really) can still take a photo of protestors and examine it manually, right?
The technology is just a tool that makes it easier, but in principle changes nothing.
I guess my point is that there isn't any fundamental change here, we have just made things easier. Maybe before, compiling facial databases if everyine was just impractical, and now it's easy.
On a scarier note: anyone can do this. You can tell the police to pinky-promise they wont use it, but nothing stops me or you or a corporation from taking photos and identifying the people on them.
