“Charles Napier, the British army’s commander in chief in India, faced with local complaints about the abolition of suttee (the Hindu practice of a widow sacrificing herself on her husband’s funeral pyre), replied ‘You say that is your custom to burn widows. Very well. We also have a custom: when men burn a woman alive, we tie a rope around their necks and hang them. Build your funeral pyre; beside it, my carpenters will build a gallows. You may follow your custom. And then we will follow ours.’”
