Whatever these people do sets precedent due to the public exposure they get. If they start more (physical) confrontations, the more extreme among their supporters may see that as an invitation to become less peaceful. The administration would see that as a justification for cracking down harder. Protesters that are breaking the law would be the icing on top.
Tim Waltz's decision to increasing the readiness of Minnesotas National guard shows that the situation is extremely tense and the opposition to the administration is forced to walk on eggshells.
It's a near perfect catch: do too little and they won't care and continue implementing their playbook. Do too much and they can and will move faster.
