Over the years I have watched a few Public Inquiries and unfortunately it is very rare it proceeds to criminal convictions.
What helps me (although it might nor help you or the sub postmasters/mistresses) is these people are now part of history - in a bad way.
To give you an example: Covid Inquiry and Boris Johnson.
BJ only aim in life was to be known as one of the greatest Prime Ministers, along with his hero Winston Churchill.
Because of the Covid Inquiry and all the other investigations and reviews, history will forever show he was the worst PM in history.
His aim of of his name and legacy to be linked with Churchill will never happen.l, and I find comfort in that.
In this case, Post Office scandal.
I like to take comfort that Paula and others will forever be known in history as causing the biggest miscarriage of justice in the UK.
Her name and legacy will not be what she wants, I.e. to be seen as a charitable, religious, dedicated her life to public service etc.
Being responsible for ruining the lives of thousands of people- this is her true legacy
In fact, she is also in the ranks of people who had their OBE removed or forfeited their honour. I know strictly speaking she "voluntarily" gave it back, but we all know she didn't really want to.
She is in company with the likes of Jimmy Saville, Rolf Harris Harvey Weinstein, etc.
Not sure if that helps.
