He initiated the National Memorial for Peace and Justice in Montgomery, which honors the names of each of more than 4,000 African Americans lynched in the 12 states of the South from 1877 to 1950. He argues that the history of slavery and lynchings has influenced the subsequent high rate of death sentences in the South, where it has been disproportionately applied to minorities. A related museum, The Legacy Museum: From Enslavement to Mass Incarceration, offers interpretations to show the connection between the post-Reconstruction period of lynchings to the high rate of executions and incarceration of people of color in the United States.
