We cannot prevent future elite assaults of this kind. We can only delay and dampen the next round by punishing those responsible, to the best of our abilities.

Free speech (with or without permission) exists so that we can punish with words, images, disclosures, logic… and , yes, ridicule and humiliation; and so we can catalyze individual resistance and organizations of opposition.

Establishment collaborators, enablers and planners must be exposed and destabilized. The false self-image they adopt and project should be challenged. This is often the only way we can influence those agents away from their compliant and harmful behaviours.
People know this instinctively, which is why we vote to punish, rather than to reward.
