Well, thats the only possible scenario I think that could reasonably lead to a conclusion that she's a threat. However, I dont know if the law allows the jury to take into account facts not in existance at the time of their deliberation when considering 'future danger'. I know, its splitting hairs but these are the type of issues that get appealed.
I have no probs. with a death penalty for people who were clearly sane, and clearly a future threat. This woman is neither, especially if they lock up 'ol Russ too.
