Final answer:
Heck Tate does not shoot Tim Johnson because he believes that Atticus Finch has better marksmanship, prioritizing the safety and well-being of the townspeople in Harper Lee's 'To Kill a Mockingbird'.
Step-by-step explanation:
The question refers to a scene from Harper Lee's novel To Kill a Mockingbird, where Heck Tate, the sheriff of Maycomb, does not shoot a rabid dog named Tim Johnson. Heck Tate does not shoot the dog himself because he knows that Atticus Finch, another main character, is a better shot than he is. Despite being the sheriff, Heck Tate recognizes the importance of ensuring the safety of the townspeople by delegating the task to the most skilled person available. This act shows his practicality and humility, as well as his trust in Atticus's shooting abilities.
