This is “To kill a mockingbird” forgive me if my answer is not what you were looking for because It’s been awhile since I’ve read it, from what I remember:
The accusations against Tom Robinson are (in my opinion) False. Based of the evidence, the Ewells are racist people who prejudged Tom before getting to know him, assuming all African Americans are guilty of the same distrust-worthy actions. Tom Robinson also was disabled and thus the accusations against him are hard to believe.
(Sorry if I spoiled, I don’t know how far you are in the book)
hope I helped :)
