Name any other person in this saga beside Epstein himself that was convincingly involved with underaged girls. There is none to my knowledge as otherwise an automatic persecution would be mandatory.
First, before the files were released my take was the files won't necessarily be a smoking gun but it will prove associations i.e. there won't be enough to file criminal charges. That might still be correct, but the files show a lot of very unsavory things going on. Without explicitly detailing criminal activity, the emails are sketchy as fuck.
Secondly, to address your question, if Epstein was recruiting from a certain age group and these were the
same girls his friends had access to, why would the girls that others slept with not be underage? The photo of Andrew and Virginia Giuffre is already out there. Andrew's excuses have been so bad, from denying ever meeting Virginia to he can't sweat, that his cageyness is part of why he's faced some consequences. That Giuffre was 17 at the time she met Andrew doesn't address her sexual assault allegations or his defensiveness on the matter.
I'd also add no sane person, be it Andrew who settled the Giuffre case, or Michael Jackson, settles a lawsuit involving child sexual abuse if they are innocent. The reputational damage is just different.
So, in closing, I don't put it past
any of Epstein's associates that they were with underage girls when they were drawing from the same pool as Epstein. Yes, men like access to easy sex. Above-board men join exclusive escort agencies. Elliott Spitzer and David Vitter, two politicians whose careers were tainted by revelations of hiring escorts, are not in the files as far as I know. The ones in the files and Epstein himself are a product of power giving one an aura of invincibility because everyone knows power corrupts.
