No it does not. A 'No lone zone' does not mean everyone who enters must be armed. It is an area where everyone, at least two or more, must be in visual contact with at least one companion.
For example, whenever I had to enter a 'Victor Alert' HAS, neither I nor my companion can be out of sight of each other. If in the course of duties we must be on different areas of the aircraft and out of sight of each other, then two or more people from the outside will be called in so everyone is in compliance. Usually if the lower half of the body is blocked from view, we generally excuse that, but we cannot excuse the upper half because of the hands and the head, obviously. If someone refuses to obey procedures and/or orders and cannot be persuaded to leave the area, then we are authorized to use whatever force necessary to remove the person, and that include lethal force if it come to that. I have never had any 'bad' experience in a VA HAS, the armed cops have a pretty good deterrence effect.
