If you want to really know your country, Memphis is a good place to start. Artists such as Howlin’ Wolf and Elvis Presley brought American culture together and sent it around the world from a studio only steps from where a slave trader was celebrated in a city park. Martin Luther King Jr. marched for economic justice, climbed to the mountaintop, and was taken by an assassin’s bullet, all within a triangle separated by a couple of miles.

Randall Mullins and Sharon Pavelda founded a project to identify and memorialize lynching sites in Shelby County, and helped create a community of supporters, from the National Park Service to the local NAACP, preachers and politicians, activists and academics.

As people are being shot while shopping and praying and driving because of what they might or might not believe, or just because of what they look like, it serves us well to remember that we have plenty of homegrown terrorism in our history.
