A video and a man who when LE arrived was unconscious, unresponsive,wasn't breathing and had a faint pulse which soon vanished along with her viewing the video and pointing out step by step to the jury the dying process of JN from a lack of oxygen.JMO and just my experience we don’t know 100% that he was brain dead since she made her decision from viewing a video.
Again JMO and experience.
"Looks like a duck" to me too.
