At a recent IT event, I heard a revealing story during a sub-postmaster interview. In the audience was a software engineer who, during the Horizon scandal, had been a first-year software engineering student whose family ran a Post Office branch. Her technical background helped her recognize the system's flaws - this wasn't user error, but a fundamental software issue. Acting on this insight, she convinced her family to implement manual double-entry bookkeeping alongside Horizon, creating their own audit trail. The family ultimately sold their branch due to the operational burden. Tragically, the next owners, without this technical foresight and parallel accounting system, fell victim to Horizon's failures. The Post Office then attempted to blame my source's family for the 'missing' funds.
