A white Chicago policeman was charged with murdering a black teenager on Tuesday, hours before authorities released a graphic video showing the youth walking away from officers as he is shot 16 times.
The footage of last year's shooting, taken from a camera mounted on the dashboard of a police car and made public under orders from a judge, prompted mostly peaceful street demonstrations in Chicago.
The clip showed 17-year-old Laquan McDonald, who authorities said was carrying a pocket knife and had the hallucinogenic drug PCP in his system, as he was gunned down in the middle of a street on Oct. 20, 2014.
The video can be seen below. Warning: It contains graphic content.
