It is unlikely that a right-handed person would attack on the left side.
Each character's appeal to the jury will be explored thoroughly within Robinson v. Ewell, a trial based around Mayella Ewell's rape by the accused, Tom Robinson.
Tom Robinson Takes the Stand
No suh, I's scared I'd be in court, just like I am now.
As Atticus was posing logical questions against Ms. Ewell to try to locate fallacies in her story, she defended primarily with pathos. Mayella resorted to emotion, evidently displayed from her choice to cry on the stand. When interpreting the trial in entirety, Mayella rarely defended logically or with evidence, as she mostly appealed to the emotion of the jury.
Atticus's Role and Appeal
Our courts have our faults, as does any human institution, but in this country our courts are the great levelers, and in our courts all men are created equal.
Mr. Ewell took the stand after Mayella in order to give his testimony of what happened the night of Mayella's rape. Mr. Ewell, similar to Mayella, also chose to defend on the basis of emotion. Atticus genuinely took the same approach to questioning Bob, in hopes to also locate fallacies. Generally, Atticus's approach was consistent and effective.
The Justice System's Consensus
Guilty, guilty, guilty....
Tom had taken the stand with the intent to convey his innocence through honesty. While he lacked in credibility because of his ethnicity, his main goal was to develop as much ethos as possible, while upholding his truth logically. Mr. Gilmer questioned Tom throughout his testimony, and Tom only answered truthfully.
Atticus, throughout the entire trial, generally appealed with logistical and factual evidence, despite that his credibility was damaged for defending a person of color. He generally didn't show any persuasive emotion, in an effort to make infallible points. He called upon the justice system to leave behind its old policy of bias based on ethnicity, and to review the evidence.
The Justice System within the time period had seldom ruled in favor of a colored citizen. Despite that there wasn't any clear-cut evidence that Mayella Ewell's rape was on the hands of Tom Robinson, the Ewell's fallacious case was ruled in favor of. Racial bias determined the integrity of society, no matter how unjust.
