You solved the mystery for us.
All members are asking how it can be that a departmental official can come in and simply say, “We had the wrong estimation”. And your answer is, “Well, if that's the case, show us the analysis. Show us how you came to the conclusion that you set out with the wrong number in the first place, over the three years that were contemplated.”
There is no analysis, that you could find, that substantiated his claim that the department reduced the numbers because it had done so based on evidence, based on public safety. This is his testimony, not mine. Therefore, you could not find any substantiation that would backstop Mr. McDonald's testimony that they made a rational decision to reduce the number of audits based on evidence.
