"IN HER BOOK THE NEW JIM Crow, Michelle Alexander argues that the system of mass incarceration in the United States, fueled by the war on drugs, operates in a seemingly color-blind, race-neutral way to create a new Jim Crow system that forces African Americans, especially African American men, into a permanent underclass.1 I believe that attacks on Roe v Wade2 and efforts to treat fertilized eggs, embryos, and fetuses as separate legal persons will establish a system of law in which women who have abortions will go to jail. Furthermore, all pregnant women are at risk of being assigned to a second-class status that will not only deprive them of their reproductive rights and physical liberty through arrests, but also effectively strip them of their status as full constitutional persons. Here I address major changes in US law enforcement since Roe v Wade was decided in 1973 that make it likely that if Roe is overturned women who have abortions will be arrested and sentenced to incarceration. I discuss how efforts to undermine Roe and to establish separate legal personhood for fertilized eggs, embryos, and fetuses are already providing the basis for the arrests and detentions of and forced interventions on pregnant women. I conclude that these efforts, if unchecked, not only will result in massive deprivations of pregnant women’s liberty, but also will create a basis for ensuring a permanent underclass for pregnant women or, for lack of a better term, a new Jane Crow."
