Chicago releases video of officer shooting teen

Chicago: Chicago officials have released a video of a white police officer fatally shooting a black teenager last year.

The move follows a judge's order last week to release the squad car dash-cam footage. Seventeen-year-old Laquan McDonald was shot 16 times on October 20, 2014. Police say he refused to drop a knife.

Some worry the images could lead to the kind of unrest seen in Baltimore and Ferguson, Missouri, and other cities after young black men were slain by police or died in police custody.

Lawyers who have seen the video say it shows McDonald with a small knife and walking away from officers. They say Officer Jason Van Dyke opened fire from about 15 feet and kept shooting after the teen fell to the ground.
