I really don't understand why she needs to be a lawyer to continue helping people. Her value comes from her celebrity power. Even if she passes the bar, to be a really good attorney, she really needs to work under some more seasoned attorneys to learn the ropes. And even then, it takes years to be really versed in all the nuances.
I just don't get it. Just leave the mundane law work to actual experienced attorneys and continue using your celebrity status to shine the spotlight on the cases that are important to her.
