My friend worked for / with the government on city surveilance for a short stint after his time with the army. He described an example of his work as follows: An activism group was meeting in a city center and was to walk to another part of the city for a demonstration. My friend's team had video surveilance feeds all over the city to track the activism group as they walked from their meeting place to the demonstration. As the group began to walk, my friend's team was able to delay the group with Don't Walk signals. The delay was long enough for a police barricade to permanently get in the activism group's way and stop the demonstration for the day. I may have some of the details wrong or his recount may not have fully been 100% honest, but it feels as this situation is very achievable with current technology. The most worrying piece of this story is the activists are not being confronted with a human who can talk to them. They're being thwarted by a faceless group without the chance ever discuss their reasons for demonstrating. The government in this situation was able to get what they wanted in the near term, but at the expense of frustration of their citizens in the long term.
