The footage thing is a game of telephone that the internet has played with itself.

There was no footage of the cell itself, because there are no cameras in any cells except those used for suicide watch. Epstein was pulled off suicide watch.

Internet sleuths keep demanding footage of the cell itself, which flies in the face of how prisons run.

There is footage of the cell block hallways leading to and from Epstein's cell. The footage there shows no people entering or exiting the hallway. Which leads to the next part.

The guards falsified records. They were both actually asleep on the job, but had filed statements saying they were awake and alert and watching the prison. The footage showed that neither guard did any rounds that night. They didn't do rounds the night before, or even the week before. They basically just didn't do rounds at all.

They were both prosecuted for such, but got off because law enforcement sleeping on the job is just sort of accepted...

I can't find anything about a payoff.
