What bothers me about this kind of thing is not that she can join, but that if it is successful could overturn a death sentence. I am not saying it would, but that it could. I think it would require looking at each case individually even though they are joined for judicial economy. But there is always the possibility that in situations like that any ruling is across the board for all, I just don't know. But in the event that it is, and the joinder were successful (results in the remedy sought) Arias's sentence of death could be commuted to life. Again, I am not saying for certain it would, only that it could, because I do not know for certain. All we know is that if it is successful before she is sentenced, she would not be sentenced to death. The question is what would happen if it were successful after she were sentenced? Is her sentence then overturned?
Now, in the case of a death sentence overturned and commuted to life, it is just that...life. It typically is not LWOP. So it is an automatic possibility of parole (if AZ ever reinstates parole). And that's what I do not like about her possibly getting the DP. If she gets life or the jury hangs, the judge can say LWOP and it will not be overturned no matter what happens with the joinder action. That's only going to affect a death sentence. Some future legal ruling coming along and commuting death sentences to life is what scares me, as I believe Arias to be so dangerous that she must never have any chance at freedom. MOO.
I hope that is understandable; I am really tired.
