The answer whether the protest is justified is Yes and No. Yes, I believe that the massive protest, antiwar protests were justified if the protest is carried out peacefully either by placard-waving, matching or in any other peaceful ways. But it becomes unjustifiable when Physical harm is melted on people or property during the protest.
