Honestly, I was amazed at how he knew exactly what to do with this personality. It is something I have learned as a "therapeutic parent" and was literally delighted that he understood how he needed to handle her. Here are some examples:
1. Non-sense lying is for control. JA has no respect for anyone but herself. She is smarter than anyone. To keep control, she lies even when it does not benefit her. Not only that, but it is a "test" to see if those interacting with her are smart enough to catch it. If they don't catch her, she sees them as worthless and stupid. If they do catch her and hold her accountable, they gain her respect (even though she still feels brighter). JM showed her right at the outset that he could catch her on EVERY SINGLE lie and that he could prove it. He gained her respect - that's why she looked like she enjoyed it. She finally met a worthy opponent, not just another person who feel for her stuff. Without talking bad about Nurmi, he has obviously fallen for her stuff and has not taken her to task. She does not respect him. If you notice, she tests him all the time by controlling their direct and he lets her do it. Even when he tries to give her answers, she won't always take them. Control, even when it doesn't help her. Nurmi has failed her test. Honestly, I believe she has felt "safer" with JM because he earned her respect, as opposed to Nurmi who has not earned her respect and does not have leadership with her. It literally must be scary for someone like her to be in Nurmi's hands when he has failed her tests. (And, just to clarify, as her own attorney, he did not catch the gas can stuff, he failed to see the margins of the magazines - she has gotten the best of him many times on things he could have helped her on but she didn't trust him).
2. Authority. Once JM establishes control - which is essential - he must keep it. Notice that he constantly says to her, "Mam, did I ask you if you....." when she adds to questions. He is jerking the choke chain, letting her know he is still in control and she is out of line. She bulks back at him a few times, but eventually she does submit.
3. Follow through. JM also taught her from the outset that he will never bluff. Lots of attorneys bluff or hint at evidence that may or may not come in. But, every single time she has lied and he has caught her, he has followed it through ALL THE WAY until the bitter end. In every case, she has not gotten out of it without having to face that she was caught. While this irritated some people, especially when the point was useless, it was essential with her personality that he prove his worthiness to her. One of the reasons he was able to crack her was that she now is somewhat afraid of playing the same antics (not that she won't) because she knows he will prove whatever he brings up. As a result, she is giving up much sooner than in the beginning. Notice that in the interviews with Detective Flores, even when he had actual pictures, she would say "That looks like me. How can that be?" Even photo proof didn't stop the lies. Now, JM has shown her that he will prove each and every detail and it takes the fun out of trying to lie and control him.
4. He never got flustered. As a parent, this is one thing we learn right away. To have calm control. The moment we get angry or hostile or snooty, the child has "won" in their war of control. If they can control your emotions, often that is what makes them feel powerful - it often has nothing to do with the actual outcome of events. Controlling you and your emotions is sufficient to make them feel safe and in charge (also unteachable). By remaining calm, even though animated and sometimes aggressive, he never gave her the feeling of control. Even when he had to follow endless stupid rabbit trails that outsiders thought made him look like a fool, he maintained composure and saw it to the bitter end. That is critical.
In sum, I have honestly wondered who trained him and how he had the faith to do that right. It is very hard and I am sure he had to feel stupid chasing those leads all the way to the end. But, he taught her to respect him. He taught her that he had control. And, every time she is out of line, he jerks her chain again and she often submits. I think it has been brilliant and I am just glad the jury could see it.
Just want to say - as a therapeutic parent - I often have to handle lying and violence with the same calm and be willing to calmly go through lies until we get to the truth. BUT, as parents, we are also therapeutic and giving love because our goal is to change the outcome. So, I don't want anyone to read this and think that we, as parents, need to "jerk our child's chain" as JM has done with JA. He is obviously not trying to therapeutically parent -grin! He is going for pure control and I am amazed at how well he has done it.
