TL;DR Only men are agressors and only women are victims according to my nursing school study materials.

I am a new nurse working in Boston, and the Emergency nurse association has done a wonderful job of providing learning and education software that covers dozens of subjects from pediatric emergencies, to neurological trauma. They also have learning modules that cover sexual assault, domestic violence, and forensic nursing. Although they are very informative, they show a very one-sided view of those crimes, in which only men are shown as the agressors, and only women are shown as the victims. They also show them as neatly dressed, upper middle class white women (and the occassional minority) with a sullen look and a single black eye. Only one sentence in the entire 100+ pages of the modules mentioned that men could be victims as well, but insinuated that it was in a homosexual relationship. The modules also started that toxicology screens should not be done unless you feel it is a medical issue (overdose or poisoning) as evidence of drugs or alcohol in the system could be admissible in court and taint a juries view of the victim. In my opinion, alcohol and drug use should be admissible, as it lends itself towards the midset of the alleged victim, as well as their character. If high levels of crack cocaine, heroin and benzos are in the patients system, then there is a liklihood that they were impaired during the altercation.
