Enforcement, or alternative to enforcement, this scenario appears to me to be a downward spiral with an elusive upside.

The perps are not conforming to rational mentations, and probably will not. There seems to be a gamble forming based upon how many of the irrationals there might be who are willing to engage in violent resistance to legitimate authority.

If the first actors are dealt with through enforcement of laws, will that defuse the "movement", or stimulate more participation? Will they be perceived as martyrs, or criminals, and by what percentage of the general population?

How do we judge if this is a minor blip, or if it will be a plunge into chaos?

If the issue you are pursuing is only whether we should attempt to maintain a civil demeanor in the face of insanity, or if it is okay to belittle the crazies with ridicule, I do not claim to know the best answer. But it can be an effective tool to marginalize and ridicule miscreants as a hedge against their success as martyrs, as an alternative to allowing them to become sacrificial heroes in the eyes of others who might be susceptible to their delusions.
