WATCH: New Orleans Mayor Landrieu gives a frank speech on his city's history and the removal of Confederate monuments: "These statues are not just stone and metal. They are not just innocent remembrances of a benign history. These monuments celebrate a fictional, sanitized Confederacy -- ignoring the death, ignoring the enslavement, ignoring the terror that it actually stood for. And after the Civil War, these monuments were a part of that terrorism, as much as a burning cross on someone’s lawn.
