It happens because the racist Macomb jury members convict Tom of raping Mayella Ewell. Jem is devastated and loses his faith in the community members of Maycomb. Jem was feeling confident about winning the court case and even told Reverend Sykes not to fret because Atticus has already won because of the lack of evidence.
