Note that the village is "adivasi" or aboriginal tribal and therefore has basically left alone to practice its own way of living, if you could call it that; further excerpt:

The woman's family was not given even a night's time to arrange for the Rs 50,000. Once the headman ordered rape, it was a free for all. "Among those who raped her were teenagers and some old enough to be her father," said a villager, who was willing to depose to escape arrest. "Almost the entire village — including children — had joined the kangaroo court. All of them hailed it as the correct move," he said.

The village, 60km from Shantiniketan, the cultural and academic hub created by Rabindranath Tagore, is populated by adivasis and has no electricity or school. The administration has always been wary of interfering with tribal traditions, leaving the adivasis to live by their own laws. It saw a horrific humiliation of a teenage girl in 2010 for having an affair outside the tribe. She was paraded naked through four villages and anyone was free to grope her. Although it triggered outrage across the country, the Bengal government wasn't quite proactive. All the accused are out on bail.

Even on Thursday, a day after the gang-rape by up to 13 people, the village didn't show any hint of repentance....
