My experience as a PTSD sufferer is exactly how the Dr. is explaining. However, this does not apply to JA. For her to have commited this brutal murder she would have had to experience a deep trigger to set off her rage. Triggers can incude smells, sounds, etc.
There has been no evidence presented in this case to substantiate JA with PTSD. We and the good DR. only have JA's words to go buy. No witness to any extreme traumas or abuse.
Trust me if she is a sufferer from PTSD we would have seen her show signs while on the stand. No way could she have looked at crime scene photos each time without showing signs of panic, shaking, vomiting, etc. I experienced this when I did finally look at the crime scene photos.
