People stand trial every day with a plea of guilty. It's an irrelevance to the course of our justice system. People still have the right even when guilty, to stand and explain how and why, mitigating circumstances, etc. It's a cornerstone of our system, the right to a fair trial.I know what you mean but her guilt/innocence isn't in question is it? I mean she isn't denying anything. It is a tough one and I'm really just saying emotionally, this is how people would generally feel about her coming back. I doubt if you would find many that would welcome her back, even to face justice.
Also she has killed no one, should we take citizenship from anyone that has threatened to kill people? It's a dangerous route to go down.
