Indeed after spending several years of watching them at close quarters I have come to the conclusion that it is they who own and run the park, and us human gawkers are the beasts under inspection.
If this sounds familiar, it bears an uncanny resemblance to the line ElBaradei and his colleague, Hans Blix, the then-head of the UN weapons inspection program in Iraq, employed to excuse Iraqi non-compliance in the run-up to war last Spring.
But it is the inspection process itself which is likely to make the most difference: it is now clear what a well-run council can achieve, and where the badly run ones are going wrong.
