On this edition of Your Call, The Nation's Amy Littlefield discusses her new book, Killers of Roe: My Investigation into the Mysterious Death of Abortion Rights.Littlefield interviews those in the anti-abortion and pro-abortion movements to find out how conservatives successfully overturned Roe. She argues that understanding the forces behind the fall of Roe is essential to rebuilding and advancing abortion rights today.She writes: "The death of Roe was death by a thousand stab wounds, some of them shallow and haphazard, some piercing and fatal. As of this writing, states have passed more than 1,500 restrictions on abortion since Roe, according to the Guttmacher Institute. The Supreme Court has twisted the knife, upholding many of these state restrictions, including parental involvement requirements for minors and restrictions on public funding. And each time the antiabortion movement cut away at abortion rights, people died."
