The other side of that is that most of these surveillance technologies could potentially be used by the population against the police and public officials. For instance, protesters don't exactly wear body cameras, but they have been using cell phone cameras to document police violence. Many of the other technologies listed (license plate readers, facial recognition, etc..) could also be used, though it would be harder to use those things as effectively as cameras are used now.
