ST. LOUIS (AP) — Vandals are targeting memorials dedicated to the Confederacy, leaving graffiti on the monuments in parks and outside government buildings. This week, the slogan "Black lives matter" was painted on memorials in a half-dozen states. The graffiti reflects the racial tension that permeates post-Ferguson America, more than a week after a white gunman shot and killed nine black congregants at a Charleston, South Carolina church.
