US Attorney Stan Sennett wants to use this fraud to get at the whole corrupt judicial system existing within Kindle County since the days of Mayor Bolcarro. The client is Robbie Feaver. Dinnnerstein's uncle happens to be Brendan Tuohey, Chief of the entire Kindle County Superior Court. It's suspected that they use this account to pay off judges to sway decisions in their favor. US Attorney Sennett has made it quite clear that it's jail or cooperation.
Cooperation always means ratting out.
Either is tough on Robby. Ratting out, well, he's not a rat. Yet, he can't go to jail, he must take care of Lorraine. So he agrees to help with the sting as long as his partner, Dinnerstein, is protected. He claims that Dinnerstein knows nothing about what the money is really used for.
