But the authorities notified her, why should she follow up and there was no ‘truth’ to reveal.
These were allegations which may or may not be true - it would be hideously irresponsible to make the contents public as it would compromise any investigation, any subsequent trial and fail any victims.
If there was no investigation that’s on law enforcement - or there was no evidence to proceed at the time then MM couldn’t speak out.
The rupture with her father had already happened for reasons ‘good enough’ for her at the time and before this letter arrived. IMHO that would just be the icing on the cake for zero reconciliation whether the allegations were followed up, proven or unproven.
She was justified in keeping NC with her Dad if these allegations were still hanging in the air proven or unproven.
I think her miss-step here has been As Ever her communication approach. Her message has been self serving around her image and not around the victims. Less is more. If she had solely expressed sympathy and not hijacked this as a reputation management and commercial opportunity the perception of her dignity and integrity would have authentically grown.
She is taking miss-step after miss step. Did she now need to reveal the letter from 2018, did she need to put herself in the centre of it, did she need to share this letter (potentially criminal evidence) with the media. Is it all now distracting from the current stash of evidence found recently.
