Cue The Banjos

I always monitor the Texas prosecutors message board because they have some very interesting conversations about Texas criminal law. This question just got posted: I am taking a case to GJ [grand jury] next week where a father and his 19 year old daughter have been having consensual sex. . . . Should just dad be indicted since most people think, as the parent, he is more culpable? Should they both be indicted? And the ones of you from east Texas, don't act like this only happens in my jurisdiction! Responses should be here. And the Texas incest statute is here.
