Re: Depressing
This is my view as well. Bearing in mind that the burden of proving the guilt or "crime" would have been on the Post Office, at what point did the defendents legal teams not reply :
1. Defendants (presumably) all had historically correct accounts up to the point they started using the new system?
2. Defendants (presumably) all started to find and then be accused of accounting discrepancies at the point of starting to use the new system.
It's just too big a coincidence and I'm surprised it even passed the legal sniff test.
