I can let Mr. Ritchie elaborate on that, but I will say briefly that in this case, exemptions had been granted. We had neither a first nor a second level of verification in place.
We sometimes implement a second level of verification before letting people into the gallery. However, in this case, to the best of my knowledge, we had not done so. We only intervene afterwards if something happens. We take it for granted that these are people who have been invited.
