The credibility (believability) of Boo coming to help the children is accurate. It seems he has been keeping track of the children from inside his house—putting items in the tree, laughing at their games, fixing Jem’s pants, giving them a blanket during the Miss Maudie’s fire. Since Jem yelled “loud enough to wake the dead,” it would have alerted Boo that the children needed help.

Jem and Dill likely let Scout tag along to Boo's house because they care about her and want to include her in their adventures. They see Scout as their friend and want her to share the experience with them. Additionally, having Scout with them may provide comfort and support as they face their fears about Boo Radley.
Scout compares Boo's potential exposure to being like a mockingbird that should not be harmed because it is innocent and pure. Just as a mockingbird should be protected, Boo should also be shielded from the judgment and scrutiny of society.
