" the exam was performed by an in-training forensic nurse."
Ironically, I think that at some point, Nifong will throw the SANE nurse under the bus.
Because of her " inexperience " she was unable to see the horrendous lacerations and tearing and broom marks in the victim's hoo hoo.
Duke got a colposcope in 1999 http://www.dukehealth.org/news/283?search_highlight=SANE and for 25k, hopefully that included still and video capabilities.
If the SANE nurse, in training or not, was able to use photograhic evidence to document the lack of injuries , that will not deter Nifong.
He will no doubt find an " expert " witness who will see the injuries that no one else can.
