The expanded body camera program comes at a time when surveillance is of the utmost priority for Chicago police as the department cracks down on officers who have not reported broken dashboard cameras, turned on microphones or uploaded footage from those cameras at the end of their shifts. The issue came to light in the case of 17-year-old Laquan McDonald, who was shot 16 times by an officer. Five responding police cars had dash cams, but the audio didn't work on any of them.
