Livingston was one of the main organizers behind this month’s demonstration that temporarily shut down Lake Shore Drive, snaked through the streets of Lakeview and ended outside Wrigley Field. He and a couple hundred protesters said they took their anti-violence message to the North Side — a part of the city that organizers say gets more resources than neighborhoods where most of the shootings have taken place — to draw attention to police-involved shootings. Organizers also called for the resignations of Emanuel and Chicago Police Department Superintendent Eddie Johnson.
