The Long Guns

S3, E12: In his ongoing quest to join the police sniper team, Bosco befriends an embittered but wily squad veteran, Glen Hobart (GERALD McRANEY - "Major Dad"), who instructs him in the art of distance shooting. But when Hobart's emotional problems make him lose control, Bosco must endure his mentor's self-destructive tendencies. Meanwhile, Carlos is repulsed when he learns about Taylor's sexual relationship with Davis. The cops search for an armed and drug-addled thief. And Yokas' latest scary incident on patrol prompts her to ponder taking the test to earn a desk job as a sergeant.
