Yes, re-read the 4 slides. If we don't have enough information, then you shouldn't speculate that $20M refers to the total cost of the operation any more than I should speculate that it doesn't.

Fair enough.

But it still means that we're lacking so much information about this that referring to speculating on the sources credibility as a "smear campaign" is unfair to citizens who are asking legitimate questions. I don't know enough about this to even know what the numbers mean, but I'm ready to skewer people over it? We need to fill in these gaps before we start shaping public policy on the issue and examining a sources credibility is part of that process.
