None of what they said could logically lead to that conclusion.

Let's see. As I, a seemingly private citizen, do not participate in any of these "events", but find they cause my anxiety and PTSD to go completely off the rails when all I want is a low-stress way to deal with my personal needs, not repeated antagonistic interactions when these things go on (and for who knows what reason, I seem to be someone these non-peaceful people like to provoke when it is going on), it seems to my benefit to be not for things that irritate the hell out of me. I can see no case where I personally would feel comfortable with scanning of my face though, if I can help it (yes, I know it goes on). I do not feel safer with mass surveillance.

As usual, it depends. "Peaceful" is a very subjective term. Like the mostly peaceful but fiery protests in Wisconsin.
