A call from community leaders for release of yet another video of a Chicago police officer shooting a black teen.

FOX's Gary Baumgarten reports:

Chicago Mayor Rahm Emanual came under intense criticism for not releasing video of a cop shooting 17-year-old Laquan McDonald in the back 16 times. Now there's another case of a video of the police fatally shooting another 17-year-old and community leaders, once again, demanding that it be made public.

(Calloway) "We are asking the Mayor publicly as a community in solidarity to practice the transparency that he promised us we would see in Chicago."

That's community activist William Calloway talking about the shooting death three years ago of Cedrick Chatman. The cops say he had a gun. The family believes the video will show he was holding a cellphone box when he was shot.
