It is an interesting thought.
There are a lot of powerful rich men, and some women, involved in the Epstein scandal. Andrew could do a deal and tell the UK police and FBI everything.
Ironically Andrew’s Royal status could, and maybe still does, offered him a level of protection from retribution for telling all to the authorities.
I always think it is a good idea to break things down.
KC is The Crown and as such has a duty to protect it. Removing titles etc. achieves that.
KC is also a brother and with his personal wealth he can offer Andrew a place to live and an income. Sandringham is KCs private property, Windsor is part of the Crown Estates. Sandringham should not be a drain on the public purse and KC funding Andrew means he no longer is reliant on funding from wealthy backers who are also embroiled in the Epstein scandal.
KC funding Andrew can also be contingent on not doing a tell all book.
KC can afford to pay for Andrew’s private protection so there is no drain on the public finances. It gives Andrew a level of protection from assassination etc., a real possibility if he talks.
I am not in favour of plea deals but Andrew getting one in return for telling all might see far worse offenders prosecuted.
As plain Andrew there is also a question of should there be a complete reset with the press and media. No photos, no reporting, he is just an ordinary man in the street. The exception would be, just like an ordinary person, the press could report if charges are brought or there is a court case. There are a lot of men who use prostitutes, some of which will have been trafficked, who don’t appear in the press. Personally I would like the same to apply to Harry and Meghan. (Added to say as in they are treated like ordinary people and not everything reported on)
