All quite true, but they are doing it the hard way.
The first thing any "auditor" like this will ask their client is "What result do you want us to come up with?" Because the auditors would not be called in unless the client wanted a result they preferred instead. The auditors want to get paid, so they will aim to please their client first.
From there, it should have been easy. Get the ballots and machines shipped in, lock them in a room untouched, wait while drinking coffee, then give the client the report they wanted in the first place. Then get paid handsomely. Money for old rope, really.
But nope. These Ninja bozos have to go and play junior chemists and computer nerds and detectives with adult stuff, thereby ruining what should really have been a sure-fire money-spinner. And they made their client out as public dopes as well. Plus they have drawn attention to how stupid they are as "auditors". Nobody is ever going to believe their final report...if it ever even appears. It really is the most cack-handed group of bumblers that could have been assembled.
