Over the past year, I've written a number of stories about rape victims. There was the 23-year-old Indian student brutally gang-raped on a bus in New Delhi, who died as the result of her attack.

Her case was in the news again last week. Four of the men who attacked her, convicted of rape and murder, were sentenced to death by hanging.

There's Rehtaeh Parsons in Canada and Audrie Pott in California, both of whom committed suicide after the ordeal of their rapes. There's the West Virginia high school student who was raped by two football players in Steubenville, Ohio.
