Um, isn't the order of events:
- email sent
- legal case/research starts against Grillo sisters
- episode outside Scotts
- divorce
- Grillo sisters trial starts, using evidence that predates the whole throttling thing?
It would seem not.
First the Grillo sisters case starts, no mention from their legal team of drugs.
Then the abuse goes public. Divorce follows.
October the email gets sent.
Third party hands statement of Grillo sisters making drugs allegation against NL to prosecution. Court calls allegations scurrilous and not allowed to be reported
Sacchti says he believes Grillo sisters innocent, that they had NL's unspoken? permission to spend like mad. Bad character thingie allowed in court meaning allegations can be reported.
Basically the drug stuff, email and all, appears to have popped up only after the public abuse, the admission of abuse in the form of accepting a caution, NL divorcing Satcchi, Sacctchi's threat to sue NL for... not sticking up for him, or something and NL's counter threat to pull put of the Grillo case as a witness for the prosecution for the Grillo's
Nobody has done a nice tidy bullet point timeline as far as I have seen, but they are "innocent face" underlining the distinctly .... interesting.... sequence of the events.
So upshot, not a whisper of drugs untill after NL divorces Satcchi and fails to crumble in the face of all his previsouly widely reported tactics to try bring her to heel.
