Women were prosecuted for experiencing miscarriage or stillbirth even before the Supreme Court swept away the protections of Roe v. Wade. But these prosecutions have ramped up since, in both red and blue states. The stakes are ramping up too, with legislators introducing bills that would treat abortion as homicide, potentially subjecting patients to the death penalty. This week, Mark Joseph Stern talks with Karen Thompson, the legal director of Pregnancy Justice. They discuss what happens when the state decides a fetus, or even an embryo, has equal or greater rights than pregnant people. As fetal personhood legislation moves ahead in more and more red states, this concept is also seeping into the law in blue states. Women have been jailed because their pregnancies ended in a way the state disliked. Grandmothers have been prosecuted decades after pregnancy loss thanks to investigators using forensic genetic genealogy to hunt them down. As Thompson explains, a frightening frontier in the battle for bodily autonomy and reproductive rights is here, and it demands our attention.    Want more Amicus?
