1x7 - The Rookies

Responding to a robbery complaint, Webster and Gillis arrive at the building and enter into a criminal-chase. Thinking he is being fired at, Gillis returns gunshots. He strikes one of the criminals, David Palmer, only to find out that the teen is unarmed and now gravely injured. Gillis is overcome with guilt. An inquest is scheduled until the teen dies on the operating table. Gillis, on mandatory leave from the Police Squad, attends David Palmer's funeral, observing from a distance. Later that evening, Gillis receives the first of several anonymous phone calls informing him that he did not kill David Palmer; the Squad, consequently, begins further investigation. In reenacting the crime they discover that a third bullet was fired (from the gun of one of the escaped teens), which caused the fatal wound of David Palmer. The two other criminals are caught searching for the third bullet, and it is Gillis who convinces them to surrender, thereby restoring his honor.
