I doubt that you could get a Jury together in the UK for a fair trial due to all the press etc. So is the Justice system in the USA so flawed that she can be tried. Could you see a Judge in USA throwing it out ?
She is going to be tried due to association with Epstein. Weather she was involved or not seems not to matter in USA. She will be unable to prove that she is innocent (nor should she). That's not how that law is supposed to work.
In the end I think its all about getting some money from Epstein's estate and she is the "fall guy" as a means of getting it.
Not defending her, she made an error and may well suffer for it.
