In the case of a police officer charged with killing Laquan McDonald, a new development has occurred.
The judge wants to hear from a journalist.
The judge agreed to a defense request for testimony from an independent journalist.
This journalist was the first to write about the shooting of McDonald by officer Jason Van Dyke in 2014.
The defense alleges that Jamie Kalven obtained leaked documents.
The issue at hand is whether those documents contained protected police reports that cannot be used against officers in a criminal proceeding.
