In emergency rooms, nurses routinely treat individuals who have been harmed on purpose, neglected by criminals, or who were involved in accidents caused by illegal activities. Patients who have been sexually assaulted or abused; injured in or by a motor vehicle; and victims of child abuse are among those who have been shot, stabbed, or otherwise assaulted with or without weapons. Other patients who have been shot, stabbed, or otherwise assaulted with or without weapons include those who have been sexually assaulted or abused. It is imperative that, in the event that criminal activity is suspected or reported, a comprehensive physical examination, the collection of trace evidence, and the painstaking documentation of all marks and injuries be carried out without causing the patient any additional physical or psychological anguish. It is considered that taking this course would make a contribution to the reduction of medical and forensic mistakes. This is due to the fact that the rate of prosecution for a variety of crimes is lower than it ought to be (sometimes as a result of insufficient or improperly gathered evidence).
