When you are there, you are not in control. No one is, in fact. The mob mindset is in control, and in the blink of an eye it can turn chaotic. A crowd is its own entity, separate from the individuals comprising it. A crowd can be controlled and directed far better than an individual can. It can be spooked and provoked, as you see here. Flash-bang type explosives are here used to turn the crowd into a roiling mob, and boy did that mob roil. Avoid mass political protests, because the puppet masters will surely be on scene to marionette the crowd to its liking.
