Whether to Publish a Rape Victim's Name - Essay Example This raises both ethical and legal aspect in which the police might fall in the pressure of the public to expedite the findings on the people involve. This consequentially gives wrong leads and the police might end up with the wrong people. The legal aspect is that the police might face liability later upon deeper findings on how the real culprits. The editor or the news director must consider whether the rape victim is okay with the story being shared with other people. The rape aspect is a sensitive aspect and therefore requires the media to confide to the victim on whether to publish the story. Publishing the story without informing the victim is contrary to private life and amounts to unethical standards on a professional journalism career (McBride & Tom 12). Rape victims normally undergo tough situations and suffer from illnesses like posttraumatic stress (Smith 19). Therefore, they tend to shy away from anything that reminds them of the ordeal. Therefore, according to journalism standards, an editor must consider whether the victim in question is at the position of handling consequent reminders of the painful experience. This has to be weighed b understanding the victim’s background and establish prior to the
