Tonight on AC360: Gang rape victim inspires change

The December 16 crime against an Indian medical student in New Delhi has launched a growing movement. The death of the 23-year-old woman after a vicious gang rape and beating was the catalyst for protests demanding justice for the victim and a change in laws and attitudes in India.

The fury was compounded after the man who was with the student spoke out on Friday. They were both attacked on the moving bus. He could do nothing to save her from the horrific violence that led to her death 13 days later. They were dumped on the side of the road, injured and without clothes, but their obvious need for help was ignored by passersby for 20 or 25 minutes, he said.

The new details and shocking rape statistics in India - 24,206 reported in 2011 - are fueling the cries for societal change. That's one rape every 22 minutes in India. And those are just the ones reported. Learn more about this latest case making headlines around the world from Randi Kaye, and what happened in court today from Sumnima Udas at 8 and 10 p.m. ET.
