That doesn't really answer my question. What "criminal activities"? Who was involved?
Most importantly, why do we care?
Why care? I assume you would want anyone who participated in the sex trafficking of minors punished for their crimes. As to who was involved, that is the point of releasing the files, although some have been accused, indicted and even imprisoned, such as Epstein himself and Ghislaine Maxwell. It would also be beneficial to anyone only suspected of involvement in Epstein's sex trafficking and who is innocent, to have their name cleared.
