In spring 2011, a federal government employee in her 30s was sexually assaulted in the District by a man she met on an Internet dating site. At Washington Hospital Center, where she went for a forensic exam so medical personnel could collect evidence from her body, a female detective from the Sexual Assault Unit of the city’s Metropolitan Police Department (MPD) questioned the woman for three hours, interrupting her frequently in a manner — as the woman saw it — meant to discourage her from reporting the assault and to minimize the seriousness of what had happened to her.
