As I understand it, Mr. Chairman, the barrier at the top of the steps is there not only to keep pedestrians out, but the expectation is, as well, that if there are demonstrations or that kind of thing, there's an actual barrier. But as the sergeant was saying, once the dignitary has left, there's a little door that can open in that where people ought to be able to go through.
