A just legal system would be spending every available resource on the Epstein investigation. We literally have proof that a wealthy socialite was flying high ranking politicians and celebrities from around the world to a private child rape (I won't use soft language here) Island, and the best that we can do is some minion memes about it. The rot goes all the way to the top and every level of government is complicit, if not compromised, in my eyes.
I strongly believe he did kill himself, but was given the golden window of opportunity to do so. Having an assassin sneak all the way in there without a single mistake is harder and costlier than letting a criminal with no other way out kill himself.
The US is just smarter in how it kills people than Russia. Even though I'm not sure he is dead. There are many ways to fake deaths and instead move him out of the spotlight to some remote place.
Epstein could have simply been given a new life while still working for the same people.
