No there is not. Peaceful protests are not easy to ignore they are ignored. That's historical fact. To protest is to intimidate and produce fear of overwhelming violence. A peaceful protest is nonsensical and such a thing has become not a protest but a farce or a form of entertainment--no wonder the Americans love such things!

Protest-leaders will be directing violence to where they think it will be most effective, but these are chaotic environments and self-harm is always a result. The goal is to minimize that, not eliminate it, because it can not be done. It is collateral.
