Some Gransnetters say although he has behaved shabbily and unwisely, and didn't come across as particularly convincing in his interview, there is no hard evidence that he personally has done anything illegal.
That may be true but I believe it's the case that the US authorities would like to interview him regarding Epstein and the allegations of the women who accused Epstein of masterminding a grooming/trafficking sex network. It was reported a while ago that he had told friends he was upset, with the disclosure of these womens' testimonies, he would ne unable to visit the US, presumably fearing that he would be forced to help the US authorities with their enquiries.
The very fact that Gislaine Maxwell, a close friend of his also, has disappeared from public view and it seems no-one knows if she is alive or dead (or possibly someone is hiding her) indicates that others are aware that they will be seen as complicit in Epstein's criminal activities. Andrew would presumably have some very valuable information as to who Epstein's friends and contacts were and where they might be likely to be found.
Instead, he chose to be be questioned by a TV interviewer on "home ground".
I disagree with the notion that "they" are "really after Epstein" (because, as stated, he is dead). However, other men and women (who are presumably still alive, though possibly not for long) were allegedly involved in this criminal sex trade and they too should be held legally responsible for any illegal activities they engaged in. It is difficult to believe that Andrew knew and saw nothing during his many visits to Epstein's various residences. If he truly regretted being involved with this man and had been but an "innocent abroad", why not do the "honourable" thing and go to the US to provide whatever information he has to the US investigating authorities?
