This sounds like an exercise in obfuscating responsibility. Post Office management knew from 2003 Horizon was unreliable - they chose to bury the report. They lied in court about its reliability and manipulated expert statements to say the same. They also knowingly lied about remote altering of accounts and buried a report in 2017 on it. Let's not get lost in the weeds - the root cause of the injustice is Post Office management.
- tantalor 2y agoNo I really meant from a technical perspective, what caused the computer system to be unreliable. Management surely did not intend the system to be unreliable. But I see your point, it follows the next question after "why is the system unreliable?" would be "why was the system not fixed?" and the answer is "management knowingly allowed it to be unreliable". But that's no longer a technical reason so it's less interesting.

Horizon was clearly not designed to handle this based on the litany of errors users documented. Transactions could be silently dropped or duplicated etc. The system was also insecure and records could be silently remotely altered by Fujitsu staff.
