The Epstein thing is fascinating, as perhaps the only current example of an issue where nobody will trust or accept the official view of events irrespective of political beliefs.
People want the world to be more interesting than it is. People want life to be like the movies. That is the basic appeal of conspiracy theories. Plus, speculating is fun. No, seriously. It is. I get it. In this case and as usual, it requires people to assert with a high degree of confidence that they know how something works without really having any idea what they're talking about.
Obviously Epstein's death is extremely suspicious at best. However, a few things need clarifying before we can jump with any reasonable certainty to "omg murder."
First of all, the idea that an aged pedophile would kill himself in prison is plausible and given more credence by Epstein's previous suicide attempt (or maybe attempts). In a vacuum, it isn't hard to believe at all that he would commit suicide.
The question on which every suggestion that he was murdered (or was somehow the victim of foul play) hinges is: what does "suicide watch" mean in the context of the facility where he was held? This is where everyone's rampant speculation has really blossomed. Suddenly the world is full of experts who know what a Federal correctional facility's suicide watch is like.
If "suicide watch" means that someone walks past the cells every 3-5 minutes to check on the occupants, then it is entirely plausible that a person could commit suicide under those conditions.
If "suicide watch" means that the person is under nonstop observation (presumably by camera) then it becomes considerably less plausible. It would be very difficult, in fact, to believe that someone watching Epstein hang himself would neither notice what was happening nor have time to intervene.
Yet even under the latter conditions, it's not impossible that this really was suicide. Have you ever met a prison guard? They're like cops, but lazier. It's also not impossible that someone tasked with staring at a bank of monitors for hours on end could let their attention wander. Maybe the people responsible for watching him are just bad at their job. That's not hard to imagine.
With all that said, the idea of a high profile inmate on suicide watch committing suicide without intervention is highly suspicious. It makes perfect sense that ears would perk up and that everyone would reflexively question that version of events. I cannot imagine what kind of investigation could be done that would produce a result that would NOT be rejected by a large part of the population, but I hope a more complete version of events emerges. Whatever happened, conspiracy theories about this event will persist until long after this presidency ends.
