I caught the throat-slitting gesture from JA after the impact statements and the jury was excused. It was so quick, I couldn't be sure. I DID know she was crying (REAL tears, for once) and there WERE tears on her neck, so she could have been wiping them. Except ... hmmm. I got up to do something, thinking about it and then decided to pretend I had cried and had tears on my neck. I reached up to wipe them away. The first impulse is to use the back of one's hands, because that is the most efficient. If that wasn't a good idea for whatever reason, one could use the fingers (multiple) to catch the wetness. Then I tried it with the back of my thumb, THE WAY JA DID IT. It was VERY unnatural, and the only way I would do that would be if my thumb was my only usable digit.
Even so, I waited to see the video on YouTube and, yes, she DID use her thumb. Again.
That WAS yet another throat slitting gesture on her part. She can't help herself. She is about to be sentenced to die, most likely. She has just sat through listening to the family give heart-wrenching impact statements, yet she just HAS to send devious threats and/or wishes/insults to whomever she is directing them to (JM usually). She has NO redeeming qualities. None.
I would LOVE it if JM was able to show the jury a montage of all the covert messages JA has sent, the way she steals pencils, the way she gets in trouble for contraband in her cell, etc. I know he can't do that, but one can daydream.
