If that's what it was, don't you think Burrell would have used it back when he threatened to ruin him for going after Clay Davis via the driver back in the first season, instead of dumping him in the evidence room? At any rate, the FBI buddy talks about Daniels having more than he should in assets, but that's explained away at some point. And if they could have indicted him, wouldn't they have by now?
I remember thinking it would be out of character for Daniels to have taken money, and even more so for him not to have been more clever in hiding it; and in the conversation with his wife you're talking about, I didn't think they meant stealing money, I thought they were talking about political moves he'd made. I'd have to read the script to remember what it was, though.
I'll see if I can find the exact conversation where Daniels says he didn't take money, he just knew about the corruption, and post about it if you like.
And ps, long time no viddy, wassup?
