You might want to go back and reread the article. There is no way to tell if the grand jury was or was not given that information. Not even to ask the grand jurors, as it is illegal for them to talk about the case.
I would not have killed my mother if she was not asking for it, as I think I made clear. I would most certainly have done so if she had asked. As for did they or did they not ask, how would you (or I) know if we weren’t there? How would you know that they did not ask the doctors or nurses, or any random passer-by? Some doctors and nurses refused, and told on the one they think did it? Did they testify that they saw her do it? If so, why did they not interfere? Or are they just blaming the doctor who they think was willing to give lethal injections because someone did, so it must have been her?
The whole situation stinks, frankly, but I think it’s a lot more over than you know. Among other things, I don’t believe they can call another grand jury for this. Double-jeapordy, that would be.
You don’t know what evidence the grand jury received. The bulk of the article is devoted to telling us that no one knows what evidence the grand jury received, other than the testimony of the two nurses.
