It would be like if Epstein just came out on a public interview and said "yeah I hosted a pedophile ring for global elites as part of a CIA operation to get dirt on foreign nationals, in particular these ones: <insert list of names> but I didn't know what I was doing!"
I don't see how SBF can walk back all of his very public admissions to date. "Oh I was lying in all of those just to troll the internet", but then he can't make any statement in his own defense. He must really be one of those liars who believes his own bullshit, that's the only explanation for his behavior. He's totally going to jail at this point
