And in Chicago, the legal team defending police officer Jason Van Dyke from murder charges presented a computer-generated video in court Tuesday, calling the 4-minute depiction of the death of Laquan McDonald evidence that the officer acted in self-defense when he shot the unarmed African-American teenager in a hail of gunfire in October 2014. The computer-generated video did not reflect what was recorded in a police dash cam video of the actual incident. It did not include the images of other officers at the scene, and it showed Van Dyke shooting just a fraction of the 16 bullets he actually fired at McDonald. Jason Van Dyke faces two counts of first-degree murder. He is the first police officer in Chicago to stand trial for killing someone on duty in 50 years.
