In May of 1977, artist Suzanne Lacy mapped every reported rape in LA for a period of three weeks. This project, aptly named "Three Weeks in May", was part of an extended performance which Lacy utilized as a means to expose LA's problem of violence against women. As a centerpiece for this project, Lacy used a large map where she recorded every reported rape in the area with the word RAPE.
