@gregeganSF The post office scandal isn't really about the software failure, but the institutional failure of the post office legal department. They took the most adversarial possible interpretation of an adversarial legal system - their job was to get that guilty conviction at any cost, including deliberately quashing any evidence or investigation that might cast doubt on their prosecution. The software flaws went undiscovered because the PO was actively blocking any possibility of audit.
@Qybat That's my point. Bad software doesn't cause harm by magic, it causes harm because the institutions that actually deploy it can't be relied on to do what they should to detect and fix the problem.
In turn, though, it's also widespread naivety and/or dishonesty about how badly software can actually be wrong that enables these institutions to pretend that it can't possibly fail that badly.
