Keeping that in mind, his death objectively required a number of contrivances of circumstance that are notoriously atypical for those being held for similar accusations. These circumstances are suspiciously consistent with what's required for something nefarious to have occurred. But if all the law enforcement personnel were working at the baseline expectation of their profession (not the higher expectations that law enforcement aspires to meet), Epstein's death is statistically improbable.
Like I said above: federal prisons are run like shit. You're giving the Federal Bureau of Prisons far, far too much credit for competence. It's one of the worst-run parts of a government known for not running things well. Problems with the prison system and its personnel generally only come to light when huge fuck-ups like this happen. The kind of grand conspiracy being floated around is far more statistically unlikely than the fact that the guy hung himself because he wanted to be free and clear. This kind of shit happens all the time in jails and prisons. If someone really wants to kill themselves, they're going to make it happen one way or the other.
