If you prefer to think of NAD as a protest, it can certainly be explained that way. Rather than protesting by carrying signs, or by marching, citizens will protest by going on shooting sprees. Armed with their own photographic or videographic cameras and recording devices, ordinary citizens will dish out some accountability by taking pictures of people who are representatives of organizations who are taking pictures of them. Another equally valid interpretation is that NAD is an agreement with the status quo rather than a protest against it. In this interpretation cameras are good, so let's have more of them.
Pictures are good, so let's all take pictures.
If a department store is such a dangerous place that cameras are needed, then so be it. What's good for the goose is good for the gangster. Everyone shoots everyone and we're all happy. Now is the time to allow the Bigs to define themselves. A. Taking pictures of the surveillance cameras will cause models to appear very quickly for you to photograph.
