If there were other staff members present at the jail who knew about the assault and did nothing to help the woman or report the matter, then they should certainly be held accountable for their neglectful actions. Ignoring a person who needs help is inhumane, and there should be punishment for such behavior.
Isn't it the case that anyone who does anything to hide a prosecution of a criminal also liable? The people involved may not deserve the same sentence as the rapist, but if the staff were doing everything in their power to protect him, they are every bit as liable as the rapist.
The staff who failed to help the woman who was assaulted in police custody should be punished just as much as the officer who committed the assault. They did not provide any sort of medical or counseling services to the woman and thus failed in their duties when they were needed the most. They took their jobs with the understanding that they would provide their services regardless of their personal feelings towards victims, and their appalling lack of action demonstrates that they cannot be trusted in a position that requires a high amount of trust and compassion.
No one should ever be the victim of sexual assault while in jail. Maybe someone is rightfully serving time for a crime, but that is no excuse to subject them to such brutal treatment. When staff at a jail learn about a sexual assault that has taken place, they must take appropriate actions immediately; providing medical treatment and counseling to the victim. If the jailers ignore the victim of a sexual crime, they should be punished along with the perpetrator.
