I was there when a tourist dumbly tried to cross through the ropes that separate the guard’s walk from the public.
The guard’s first action was to confront the tourist and make a declaration, as I recall being to the effect “The visitor will please return to the other side of the rope barrier!” The guard’s rifle was held across his chest.
However, when the tourist persisted and frankly at that moment didn’t yet understand what was going on, the guard next assumed a stance with his rifle pointed at the tourist, and repeated the declaration.
The tourist then got out of the roped in area.
WOW! I’m surprised the ACLU didn’t get involved. Good for the guard!
