Throughout my life I have seen, and sometimes participated in, peaceful civil disobedience in which sitting and linking arms was understood by citizens as a posture that indicates, in the clearest possible way available, protestors’ intent to be non-violent. If example, if you look through training materials from groups like the Quakers, the various pacifist organization and centers, and Christian organizations, it is universally taught that sitting and linking arms is the best way to de-escalate any confrontation between police and people exercising their first amendment right to public speech.
