Tio Hardiman knows Chicago's killing fields better than most people.
The director of CeaseFire Illinois keeps tabs on violent conflicts across the city. He and 120 workers broker truces -- sometimes literally getting between gunmen -- to stop the shooting.
So Hardiman's opinion on whether Chicago should allow the Illinois National Guard to safeguard the city carries some weight.
"It's a good scare tactic," he said. "But the brothers would unify to fight the system. You would have a throwback to the Black Panthers."
