The PD is to prevent damage to a culture? The culture is gone, no damage.
Up ahead and around the corner there is a rapist. You can "turn him off' by removing him or destroying him. Or you can erect a sign warning others of his presence and intentions.
Now the rapist (like the people who built the monument) may think that his actions are just fine. If you do nothing, you agree with him.
Not all rape is physical.
