Body cam video spurs policy scrutiny in St. Louis teen shooting

New body-worn video released by the family of Emeshyon Wilkins shows a St. Louis officer fatally shooting the 17-year-old in the back after a brief chase; an independent analysis contends the pursuit violated department policy and that the officer did not identify himself or warn of a gun, contradicting FIU statements. The family has filed a lawsuit seeking damages, and the police department has not commented due to pending litigation.
