I'm explicitly allowing for Schneier being a "special" person, and not escortable into a secured space, as he is a technical expert and in close and continuing contact with some people with lots of very hated stuff, specifically in loving leaking classified info. A normal person would be a lot more escortable. It is mostly up to your facility security officer and organizational policies; I don't know how the legislative branch handles any of this.
