As the son of an Alabama cotton farmer, I grew up 100 miles from Ms. Lee’s hometown of Monroeville, so it was easy for me to identify with life in the fictional town of Maycomb. The Tom Robinson incident in the book was representative of the type of “justice” African Americans could expect at the time. I became aware of this truth when I was still a teenager.
I remember the morning my father told me that Clarence Williams, a black man who drove a tractor on our farm, had been arrested for driving drunk. Over breakfast, he asked me to try to get Clarence out of trouble. When I asked Clarence what happened, he told me he had struck a concrete median after his car had a mechanical problem. He was dizzy from the collision when a state trooper stopped and pulled him out of the car. The trooper accused him of being drunk, hit him with a blackjack and took him to jail.
I thought all I needed to do was explain to the judge what happened. I’d always figured that if you told the truth, you’d receive justice. Clarence and I met with the judge – a justice of the peace who held court in his country store from behind the cash register – and we told him what happened. Without hesitation, the judged declared Clarence guilty and fined him $150, not a small sum considering Clarence was earning $5 a day.
