Peaceful protests, new questions arise after additional Chicago shooting videos

Following the release of a video showing the fatal officer-involved shooting of a black teenager, hundreds of protesters took to the streets of Chicago on Tuesday night. Some shouted "16 shots," referring to the number of bullets allegedly fired during the Oct. 20, 2014, shooting of 17-year-old Laquan McDonald by white Chicago police officer Jason Van Dyke. The protests continued Wednesday in Chicago's business district, The Loop, as demonstrators peacefully chanted and marched through the area.

New footage of the shooting was released Wednesday from the dashboard cameras of four additional police cars that responded to the incident, including Van Dyke's vehicle. That brings the total number of clips released to five, with footage from the three other squad cars that were at the scene during the shooting yet to be released.

The videos in question have little audio, something the Chicago Tribune notes should not be the case; while some videos include siren sounds from outside the vehicle, no sound of officers talking or any radio communication inside the vehicle can be heard. Only one of the videos shows the actual shooting of McDonald, while the others show the scene at various points. Van Dyke was charged with first-degree murder Tuesday.
