I have been staying miles away from the Jodi Arias trial
because there is only so much I can take. To sum it up very briefly, Ms. Arias does not deny stabbing her boyfriend (or ex-boyfriend, it's not clear which) 27 times, shooting him, and then slitting his throat. She is claiming "self-defense" and no, that is not a typo.
As is almost always the case, the defense has shifted away from what the killer did to what, supposedly, she was thinking. This has the advantage, from the defendant's point of view, that, while that a guy with his head nearly cut off can show up in a photograph to be shown to the jury, the defendant's mind can't, so you can always spin some yarn about it if you're creative enough.
It also has the advantage of allowing the defense to call psychiatric "experts," one of whom I have disrespectfully labelled a "shrink" in the title of this post. But I have my reasons: The shrink is now testifying about one area of her expertise, to wit, whether Snow White was an abused woman. And no, I am not making this up.
