The Standers do not come across as neutral witnesses at all. They sound rehearsed.
I agree. Hers particularly sounds as though it's a novel she's narrating. Her choice of language is interesting.
However, she's known she'll be appearing in a court for months, possibly a year. I'm not surprised she's gone over and over it, even if it's just in her own head.
Hell, I regularly narrate my life. It's ridiculous, but sometimes I do. I think it might be a personality thing. I'm not saying that makes her a more reliable or less reliable witness.
Do you think it likely that he stopped to clarify?
You know what, I find this extremely believable. It's almost like a disclaimer - I'm a doctor, I can try to help, but I'm not a professional in emergency trauma.
