I interpret that "lack of specifics" in Sheriff Joe's presentation as strategic. Why should he telegraph his punches?

He doesn't. But, he could show us a couple of his jabs to keep us interested.
It is noteworthy that, several times during the press conference, he said he idn't know what to do with the information or who to take it to. Perhaps if he had revealed a mere smidgen of what his team discovered, he might have enough to attract the attention of whomever's ear he wants.
I don't think I am being either unreasonable or unrealistic. If he wants our "buy-in" he neds to dangle a smidgen of his evidence. Just a smidgen.
