Philando Castile: Girl, 4, calms mother in police car

Philando Castile was shot and killed by the police in July 2016 in the US state of Minnesota.

New footage shows Diamond Reynolds and her four-year-old daughter, who witnessed the shooting, being held in a police vehicle immediately afterwards.

Officer Jeronimo Yanez was found not guilty of second-degree manslaughter last week.
