She may be lying about wanting the death penalty. Or she may really prefer it. I know if it were me, I would prefer death over many decades locked up.
If the alleged disturbance that canceled court until next week was in fact due to the defense motion to take the death penalty off the table, it could be that Jodi was upset when the motion was denied...and threw a tantrum of sorts. Or...she could have been upset that her DT filed the motion...and threw a tantrum over that.
My take on what might have happened is that Jodi simply does not want to have anyone, in particular Travis' loved ones, speak to her about her crime. Before she was convicted she had the upper hand because she could grimace, smirk, even flip the family or the prosecutor a poorly-disguised bird--and no one made her stop. Yet let the family shed an appropriate tear during testimony and a sidebar is called to put an immediate stop to it.
Jodi loved it. Jodi was the star of the show.
But now, what is she? Not a star. No longer in charge. Now she is convicted of MURDER, and her victim's family and friends might not be stopped anymore if they wish to speak to her in court.
What's a girl to do? Throw a tantrum!
As I said before, I have no problem with the victim impact statements having some limitations placed (stay on topic, don't have an emotional meltdown, etc.) but limiting the family's right to speak to the killer face to face is just one more way the court could give in to Jodi's demands. I hope the motion is denied; any nonsense Jodi claims about the family physically resembling her abuser is just too twisted to be given any consideration, IMO.
