The Gulabi Gang are pink sari wearing women in India who brandish big sticks and go after corrupt public officials and boorish men. According to this BBC news article, they come from India's northern Uttar Pradesh state's Banda area. The leader is Sampat Pal Devi, who was married at 12, and is now fighting the system with like minded women. She describes her goals like this: "We aim to empower women, promote child education with an emphasis on girls, and stop corruption and domestic violence." Here's a very good story about Sampat and the Gulag Gang and here is another. Hind Makki tweeted a picture of the Gulabi Gang which prompted me to look them up.
