Yes at some point it turned into CYA. When the leadership started realizing that there were problems with the software they started doubling down, getting even more aggressive with prosecutions, because they were trying to hide their own fuckups.

But when the ball started rolling, as the software rolled out and was finding missing funds everywhere, you'd think a normal person would have asked "are we sure there are no bugs here?" That was never done, I believe, because the software was matching the leadership's priors.
