To me, realistic understanding implies that I'm most likely not a specific target of surveillance cameras around town. Those were not set up because of me, and there is no alert in some security office when I enter a camera's field of vision. I imagine most people think like this.
A bit besides the point, but my phone has a unique identifier associated with it that is constantly communicated to my operator. It also has tons of other tracking software I have no clue about. While this is something I'd prefer didn't exist, same logic applies here.
I'm not pro-surveillance, but pro realistic understanding of it. I know it's not great, but what can you do? Go around town filming people and creep them out thinking you're making a point when in reality you're just annoying people?
