In Casey's mind right now:
"A tough day here in court with people judging me and trying to keep a straight face while I stare blankly at this monitor is still a better day than in jail.. "
This is essentially entertainment for her, remember Bozo already pointed out that she is normally in her cell for 23 hours a day.
I wonder if anyone has already told her that criminals in prison actually have their own form of justice and don't take too kindly to child murderers and pedophiles. No wonder she wants this trial to go on forever, it is delaying the inevitable, her going to prison.
