You make some very good points. I once worked in a building that had cameras everywhere. And there was a guard whose only job was to watch the monitors.
Yet we have two broken cameras in this case. I would think that two blank monitors would be hard to miss.
There are required safety checks that are supposed to be made on these things, along with any fire alarm systems installed. Someone was responsible for the cameras on that floor, in that section, at that time. And if there were malfunctioning cameras while Epstein was on that floor, it should have been reported, and he never should have been placed in that uncovered area.
