I was the foreman on a mock jury one time for a personal injury case and the vote kept coming back 11 to 1 in favor of the defendant. Most of us agreed that the plaintiff caused most of her own injuries because of her own negligence, not the company that installed her gas water heater. She chose to use gasoline inside her home to clean up some spilled paint, and the fumes reached an exposed gas pilot light on the water heater. She received third degree burns as a result of the explosion.
One juror, who we found out was a nurse by trade, couldn't get past the photographs of the plaintiff's burns. She wanted someone to be held responsible for the woman's injuries and pay substantial damages. The rest of the jurors felt the water heater company couldn't be held liable for someone bringing a dangerous flammable chemical inside her home for an unauthorized purpose such as cleaning. There are other chemical cleaners capable of removing dried paint.
Because we were hopelessly deadlocked for hours, the judge came in and read us the equivalent of the Allen charge. We weren't supposed to allow emotions or personal empathy to cloud our legal judgement. We had to let the facts presented in court guide us towards a unanimous decision, even if we felt sorry for the plaintiff or the defendant as human beings. The judge's charge worked, and we finally reached a unanimous verdict in favor of the defendant.
