Was the Titanic disaster a tragic accident borne of negligence... or a conspiracy to assassinate John Jacob Astor and make it look like an accident? A lot had to go wrong to make an unsinkable ship sink. Who paid off the watchmen that evening? Why was the captain going so fast? And did one of Astor's rivals gain a contract to sell the steel that... etc., etc.
Occam's razor is important to keep handy, and Occam's razor here should be factoring in that American prisons are designed-by-committee-and-cruelty shit that have needed a massive overhaul for decades.
How many other cameras in the facility were broken?
If cameras are broken, how would you ever learn that they are broken? Perhaps it would require an important event like a suicide to occur so that you would need to review the tapes and discover the broken cameras.
He had “come back from” one conviction before. And with what he knew he could probably have cut a deal, even gone into witness protection. The suicide theory just doesn’t hold water.
Assassinating one person by sinking a whole ship is a pretty crazy way to kill someone; it's surely far easier to just hire someone to club him when he's walking the street somewhere. However, with Epstein, there's no such similarity: he was the only one to die, and since he was locked up in prison, anyone wanting to kill him really didn't have much choice, if they wanted to get him before he testified against someone. And there do seem to be a disturbing number of things that went "wrong" for this to happen.
Anyway, I think my point stands: trying to murder someone by engineering a disaster at sea like this is pretty ridiculous; too many things have to go wrong all at the same time, which really aren't under control of any one person or small group. Getting the captain to speed through iceberg territory (and honestly, there weren't that many icebergs, they were just unlucky and happened across a big one), making sure a large iceberg was directly ahead, making sure just enough compartments flooded, making sure the radio operator on the other ship went to bed, making sure the captain of the nearby ship refused to investigate, and finally when help did arrive (and it did), making sure the assassination target somehow wasn't among the survivors. Killing someone in a prison cell where there's no witnesses except a camera or two (that "just happened" to be "malfunctioning") and a couple of guards to bribe is actually realistic and possible, especially if state-level operatives are involved.
