A circumstantial case depends on the inclination of the jury to connect the dots and make the inferences that the prosecution wants them to. Juries are much more likely to follow the prosecutor's logic when the accused is an unsympathetic, unlikeable individual. No matter how much a juror believes they can be impartial in spite of what they've heard on the news, we all know it factors into their deliberations at some level. That's what Houze is concerned about - every negative news story raises the bar he needs to clear one notch higher.
So do the likely benefits outweigh the risks? Any contest of the RO will necessarily involve arguing the MFH and Kyron allegations. The chance of this happening without Rackner putting TH on the stand is zero (KH has already said that this was more about getting TH to talk than anything else.) If TH gets on the stand and has to take the 5th on questions regarding either subject, the judge will likely make a negative inference of fact. Why contest in the first place when you know you've got both arms tied?
Again, if this were an ordinary case with no media attention and no potential capital crime, I would be with you all the way in your analysis.

Reading your bolded comment it struck me as ironic that the fact that she retained Houze in the first place creates a very negative inference right from the get go -- someone who has not been charged with anything or named as a suspect or even a poi, runs out within days of her husband leaving and filing for an RO and divorce (both civil actions) and hires the best and most expensive criminal attorney someone's money can buy. Maybe he should have suggested she retain someone less high profile and/or a civil lawyer, and just kind of waited in the wings to see how things shook out. jmoo
