A homeowner shot a Black teenager twice when the youth knocked at his door by mistake to pick up his siblings from a playdate in Kansas City, Missouri. Ralph Yarl, a high school junior, was seriously injured but in stable condition on Monday, his family said. The homeowner, who Yarl’s family say is white, was detained but released within 24 hours by Kansas City police. Demonstrators took to the streets in protest against the decision by city authorities, who insist they cannot take further action until they have spoken to the seriously injured boy.
