I saw this quote recently and thought it was quite intuitive and brilliant. The author and source are unknown.
“Cross-examination is the highest art form ever devised in the history of the human race. It is a ballet of hand and eye gestures, movement, vocal gymnastics and intellectual warfare. It is the ability to stare an enemy litigant in the eye with the understanding that you are going to take control of his mind and speech. Gymnasts and ballerinas are opposed only by inanimate objects and the force of gravity, each constant and predictable; each conquerable by rehearsal. The cross-examiner, on the other hand, is opposed by a trapped animal with the brain of a human, sometimes.”
It is because the art of cross-examination is so complex and mysterious that practice over time is required for an aggressive Michigan Criminal Defense Attorney to develop the techniques necessary for effective cross-examination.
