Dick Goodwin knows that Stempel is a loose cannon, so...?

I don't get Goodwin. He seemed to know that Van Doren was lying from the poker game but gives him one chance after another to avoid testifying and then tells his wife he doesn't care about reforming the contestants or punishing them. You can't make an omelet without breaking eggs. Unless he gets famous contestants to say the producers rigged the show and thus expose their own deception, what did he think was going to happen but the show producers lie or try to whitewash it? And the contestants who didn't testify would be assumed guilty. I think Martin Scorsese's character is right all along. The public doesn't care about who rode with Paul Revere, the name of his horse, who loaned it to him, or its sex. They just wanted to watch the money and the drama of ridiculously difficult or obscure questions.
