I keep wondering about that. Would she protect him, because they are married? Would she protect him because they are both crazy, and she believed he was a prophet? Would she protect him because she knows she is just as guilty as he is?
I guess time will tell.
It's not only a question of whether she would "protect him." If they are married, she has no choice in the matter -- as far as I know, spousal immunity comes into play in his defense even if she wants to cooperate.
Which brings up an interesting point. If she has been "cooperative" with the police up to this point, and has helped them find any evidence that could be used against Brian Mitchell, then every piece of that evidence can legitimately be thrown out of court if his case goes to trial.
Something else to think about for those of you who have been questioning the competence of the SLC police in this case.
