Sanford didn't take a plea bargain. He pled not guilty but lost and was convicted. (But his helper Larrue did cooperate with police and testified against Sanford in exchange for lower charges) So that's why I'm speculating that Sanford can probably only spill the beans on Mimi after any appeals are exhausted. Talking about her involvement isn't possible while he's still trying to pretend he's not guilty.Once he took the plea bargain and pled guilty, he is protected from any further prosecutorial action by double jeaprody. So, he would not need to worry about self incriminating testimony etc.
