Final answer:
The question is about the book 'Monster' by Walter Dean Myers but was mistakenly mixed with Ralph Ellison's 'Invisible Man'. Due to this error, an accurate answer cannot be provided without the correct literary reference.
Step-by-step explanation:
The question posed appears to be about the book Monster by Walter Dean Myers, not Invisible Man by Ralph Ellison. Unfortunately, due to a mismatch in the literature references provided (Invisible Man) and the actual question posed about Monster, an accurate and detailed answer cannot be provided. The correct book should be referenced in order to address the actions of characters Asa Briggs and James King during Richard Bobo Evans' testimony.
