Police chief defends officer in shooting of Philando Castile

St. Anthony, Minnesota Police Chief Jon Mangseth defended his officer who shot and killed Philando Castile during a traffic stop as level-headed and skilled in an interview with The Associated Press, using his first public comments about the July incident to paint a contrasting picture of the officer shown screaming expletives while pointing his gun at the dying man in livestreamed footage of the shooting's aftermath.
