You keep on saying that, and its a curious conclusion.
You are up for 25 years in prison. Feds say help us or we ask the judge to throw the book at you. You buckle and say ok ok, I know about this thing in Houston. Feds say, ok, give us more. You say..uh...they used to tell us not to throw out stars. Feds say, come on, if you don't start spilling everything you know, we aren't helping you. And so you start throwing out anything that you think might stick, anything to make them happy. Stern, a lawyer himself, was right about this being Donaghy "singing". The problem is that we do NOT know whether he really had anything to sing about, or whether he knew that if he did not come up with something, he was going to jail for a long time.
He tagged a public incident. His source is dubious -- why oh why would another ref tell him that he meant to cheat? He wasn't there at the incident. He provides no details that you or I could not have provided. And he only has a handful of incidents to report. If he had 20 incidents, there would be no reason to add a 21st. But he only has 2 or 3, and none that really raises to the level of dishonest conduct.
And this exact dynamic happens all the time in the law. All the time. A drug dealer is brought in. You lean on him. Maybe he gives up a small fry. You lean on him some more. He tries to comply by giving you the names you want. But does he actually know those names? Or does he actually just know that you want them? There are a lot of bad cases that turn upon this very dynamic. The fine line between getting everything out of somebody that they know, and in going beyond that and starting to get lies and exaggerations and hearsay mixed in as well.
