They will, more and more frequently, until revolution breaks out, IMO. I don't think there is a solution to this. It's a common pattern and we see it in many countries right now, unless they have already fallen into civil war; more and more violence more often, as in Sri Lanka (Ceylon). Burma has already gone over into war, so has Ethiopia; the pattern of increasing violence in China is worrying, most of it starvation and gross imprisonment in their homes enforced by the government.
I just suddenly saw it. We're in the lead-up to revolution and that means more and more violence until there is a triggering event, a tipping point. Lincoln's election, or Lexington-Concord, like that.
Nothing can solve a lead-up to civil war, so we just have to wait it out.
