Heck Tate is the sheriff of Maycomb county. He decided not arrest or even file a report regarding Boo's involvement in the death of Bob Ewell. Heck knew the attention of people in the town, including his wife, would destroy quiet, misunderstood Boo Radley. He had Atticus Finch shot the rabid dog, because Atticus was a better shot. Much to the surprise of the children, Heck called Atticus with "One-Shot Finch".
