I was on a jury for a murder trial, and so I have some insight into how juries work. At one point, when I was splitting some hairs and discussing the meaning of some small details from the evidence, one of the other jurors got impatient and reached for the coroner's photo of the victim. "Someone died here, you realize."
You should have taken him to a side and told him to go watch 12 Angry Men when he gets home.
