Do you think it was okay for Heck Tate and Atticus to lie for Boo? What might you have said if you were in this "tight" situation? Would you have lied? Or told the truth?

The truth about Boo Radley would have harmed Boo himself. Boo could not handle the attention and it was better for all involved that Bob "fell on his knife". I think this was the best course of action. Sometimes the truth can do more harm than a simple lie. Boo would have withered with all the attention.
