“In the wake of the controversy over removing American monuments to the Cult of the Lost Cause of the Confederacy, Memento Park is not a bad model for us to consider following now — although certainly there are others. The dispute, which exploded into bloodshed, death and grinding national shame in recent days, demands hard thought. Decisions need to be made. Unlike sculpture, civic monuments are less the product of an individual artist than they are collaborations of entire societies. Civic monuments solicit a collective moral response. They invite an audience to affirm and applaud what it sees.”
