Finding no evidence of any connection with the Hoffa campaign Cherkasky dismisses the whole thing without even suggesting that further investigation into these strange transactions might be appropriate. No hesitation, no qualification. A definitive answer of 'yes' however is not possible. The Election Officer cannot definitively negate the possibility of some unitemized cash as having come from an improper contributor. You may not be able to figure it out, but what he actually says is that, despite his boldface pronouncement, he can't tell for sure.
Cash transactions are suspect because they are almost impossible to trace.
But how much exactly That's a lot of money. In a report otherwise bulging with statistics, this one is missing. Cherkasky concluded that he and his investigators did not find sufficient hard evidence to bar Hoffa from the election rerun. But even that finding or lack of one, right or wrong, hardly justifies the overall tone of his report and the impression it leaves. But he goes further and provides the Hoffa forces with a clean bill of health, not a total whitewash or complete vindication, but enough to supply them with campaign ammunition.
