Can we please stop bashing the judge for "allowing" questions that she has no choice but to allow? It is not the judge's fault that JA/Nurmi chose victim-bashing as part of their theory of the case and she does not have any right to stop them from doing it.
The point of these questions IMO is to show that Jodi and Travis had a "secret," twisted relationship totally in conflict with Mormonism, which created this huge tension and feelings of "debasement" for Jodi, and that Travis helped set up that situation. The jury is supposed to think that, combined with Jodi's mental illness, this stressful situation pushed her over the edge into premeditated cruel murder. Voila! Mitigation!
IMO this ain't gonna work. But JSS has to let them try even if it makes her puke.
Normally, the client is in charge of the "facts" and the goals, and the lawyer is in charge of getting from here to there. But IMO the strategy of linking up the sex facts to the goal of a life sentence was probably Nurmi's, based on his experience in that area.
