Oh in that case, just give the people whatever they want. I assumed the discussion was about the scenarios this tool was designed for, aka not "unarmed and nonviolent" people.

The problem I think needs a solution is a group of mostly good people being riled up with the well-studied herd mentality, laced with people doing bad things. You want to be able to stop the few bad people (without killing, obviously) with minimal disturbance to the good people, but at any time you cannot know who is good or bad (i.e. you can't enter the crowd to target specific people), and at any point the good people can turn and become malicious actors, contrary to how they'd behave in most circumstances.
