All police departments in India are rotten, with their rules, procedures and attitudes directly descended from colonial rule. But having lived in TN for five years, in my experience that department is the most rotten of any state I've lived in - worse than Delhi, MP, Karnataka and Haryana. I remember the time when I had to accompany a friend for the lodging of a missing complaint, because police stations in Chennai were simply not safe for a woman to venture alone to in 2004.
