"One often-cited abuse of the nullification power is the acquittal by bigoted juries of whites who commit crimes (lynching, for example) against blacks. That repellent practice cannot be directly arrested without jeopardizing important constitutional protections-the double jeopardy bar and the jury's power of nullification. But the revulsion and sense of shame fostered by that practice fueled the civil rights movement, which in turn made possible the enactment of major civil rights legislation. That same movement spurred on the revitalization of the equal protection clause and, in particular, the recognition of the right to be tried before a jury selected without bias. The lessons we learned from these abuses helped to create a climate in which such abuses could not so easily thrive."
