When I was young, women were raped on the campus of a great university and the authorities responded by telling all the women students not to go out alone after dark or not to be out at all. Get in the house. (For women, confinement is always waiting to envelope you.) Some pranksters put up a poster announcing another remedy, that all men be excluded from campus after dark. It was an equally logical solution, but men were shocked at being asked to disappear, to lose their freedom to move and participate, all because of the violence of one men.
