Looks like this is a case of dereliction of duty. No one was in the area of Epstein's cell during the time he was left alone, according to surveillance video. The union guy can blame understaffing or whatever, but it seems to me the guards were busy sleeping and surfing the web when they were supposed to be checking on prisoners -- not just Epstein -- for 8 hours. And then they falsified records to show they had checked on him. and other prisoners during those 8 hours.
I'd say this shoots a big hole into the theory that Epstein was murdered.
