A political Halloween decoration has people in Shelbyville outraged. An unknown person hung a dummy from a tree at the corner of 130 and Snell Road. The dummy had a GOP outfit on, a white dunce hat, and a Marsha Blackburn sign hanging from it. Under that, there’s a sign reading “Stop the Hate. ”Billy Grimes has lived in Shelbyville for eight years. He couldn’t believe his eyes when he spotted the dummy eerily swaying in the breeze as he drove across a bridge.
