Van Dyke, journalist in Laquan McDonald case in court Wednesday

CHICAGO -- The Chicago police officer charged with shooting and killing Laquan McDonald faced chants of "murderer" from more than 12 protesters as he headed into court on Wednesday.

Jason Van Dyke is accused of shooting McDonald 16 times in 2014. The independent journalist who helped break the story also appeared in court.

Jamie Kalven first questioned why the police's account of the shooting was not supported by a witness and dashcam video.

Other journalists then sought the release of the video.

Defense attorneys want to know who Kalven's source was because they believe that the source violated Van Dyke’s rights when they handed over statements the officer made to superiors on the night he killed McDonald. Those leaked documents contain legally protected information.

But, the state and Kalven's attorney argued there is no evidence to support that.

Attorneys continue to battle over what is protected information and who had access to it.

Kalven did take the stand, but his testimony was brief. Kalven has said repeatedly that he will not reveal his source.
