Book excerpt: “A work of striking political and legal imagination.” —Aziz Rana, author of The Two Faces of American Freedom Robert L. Tsai offers a stirring account of how legal ideas that aren’t necessarily about equality have often been used to overcome resistance to justice and remain vital today. From the oppression of emancipated slaves after the Civil War, to the internment of Japanese Americans during World War II, to President Trump’s ban on Muslim travelers, Tsai applies lessons from past struggles to pressing contemporary issues.
