Yesterday the ACLU released a new report, Worse Than Second-Class, on women prisoners held in solitary confinement. Through surveys of prison practices and testimony from women who have spent time in solitary, the report presents a picture of institutional violence not only perpetrated against women at skyrocketing rates but which harms them in unique ways. Our understanding of solitary has been based off men’s experiences of it, but expanding the range of narratives is necessary to understand the full extent of the cruelty. As ACLU senior staff attorney Amy Fettig told me, not only is solitary confinement often overlooked by its use against women has been rendered nearly invisible outside of prison walls.
