> I wonder if the Fujitsi developers, far removed from the Post Office staff, have ever stopped to consider that the software they wrote ruined the lives of so many people.

They may not even be aware that they worked on this. Or they may have relayed concerns about schedule pressure making errors inevitable, or may be working in an environment where no such concerns can ever be raised.

It seems likely that they're working in the before-testing times which correlates strongly with risk of the above.

I wonder about the procurement process that lead to Fujitsu supplying the UK post office. This might be an instance of the public sector picking the cheapest from N bids then looking surprised when cheapest turns out to mean crap.
