I would welcome collective responsibility only if it means collectively acknowledging the harm that was done, listening to those who were harmed, and committing to repair, not just punishing those in power. Restorative justice asks each of us to examine how we contributed to or normalized the conditions that allowed this harm, and then to take concrete, shared steps to repair relationships, redistribute power, and change the structures that made the reckoning necessary in the first place.
Unlike penal justice, restorative justice is idempotent and we shouldn't fear its application.
