How do I even have access to this area? Take those people in the hall, for instance. They won't worry when a fellow employee shows his face there. Anyone they don't recognize would be questioned. Or, they would just call security.
At least the vid connected the in house DGE office with the brig you said didn't exist. The cam doesn't have to be fancy, it just has to get the job done.
Did you really see their faces at all?
Golly, I didn't know my Samsung Galaxy had enough pixels for that. Anyway, most of what you saw there were some feet.
