As you write your report, make sure to include a non-biased voice in your writing. By the end of our reading of the trial, most of us as a reading audience find frustration with the town. Be careful not to approach your listening audience with a view or perception that they would not appreciate; taking Tom's side, for example would hinder that audience.
Mention the details as reported by Bob and Mayella. Then mention the details shared by Tom. Note these details all conflict. Of great importance would be the fact that Bob Ewell appeared to be a dominantly left-handed person.
It might be fun if you get to record this assignment to approach it as if it was a sporting event, so you can give it a play-by-play feel.
