You definitely should blame the contractors.

It's become very clear as the public enquiry has progressed [1] that Fujitsu were:

- aware of several bugs - including ones they'd fully understood the cause and mechanics of - that would induce double-counting of transactions

- aware that criminal prosecutions were underway against users of the system in which just such double-counted transactions would clearly have had a material impact on the case and the evidence aduced

- failed to raise the above in a timely manner, either to the Post Office who had directly requested audit logs, to external auditors, or to the justice system itself
