"At some point a tall, thin man appears in their midst, dressed in papery green hospital scrubs - an ID bracelet on his tattooed wrist and EKG leads still stuck to his chest. He picks up a poster and holds it high in the air.
'I got shot last night,' he says, pointing to a piece of gauze taped to his right cheek. 'I still got two bullets left in me.'
His name is Devrone McKnight - the 23-year-old was driving himself home from the hospital when he saw the ceasefire volunteers by the side of the road. He says he's ashamed. He'd heard about the ceasefire effort but had made no plans to participate.
'Now I'm a victim,' he says. 'From now on, I'm supporting this.'"
