She can serve her time after she is executed in Alabama. The good citizens of Alabama will not use kid gloves on her. She has a date with needle in her future.
This is not so much Massachusetts coming to their senses as it is a play to keep her from being executed. I think they know their case in Alabama is open and shut. They'll argue that since she did the crime in Mass first she should do the time in Mass first. Please don't send her back here; take care of business in Alabama.
