What do polygamy, prostitution, and pet inheritance have in common? For the final episode of Hold That Thought's 10-part series on American Identities, Adriennne Davis, professor of law and vice provost at Washington University in St. Louis, discusses the role of law in regulating intimate relationships in the United States. According to Davis, personal attachments, identity, and citizenship are fundamentally linked, and in her research, she envisions concrete ways in which the U.S. legal system might be more accepting of irregular forms of intimacy.
