True or False: Officers should use hand movements to help prove their point.

• A. False
• B. True
• C. Sometimes
• D. Only in certain situations

Answer: (A)

Nonverbal behavior during testimony should not be used to “prove” a point. Hand movements can be read differently by jurors and may come across as trying to persuade rather than simply recounting facts. The credibility of a witness rests on clear, accurate, and complete factual statements, not on gestures.

Best practice is to describe what was observed in precise words, rely on the evidence and procedures, and use gestures only in a neutral, minimal way (for example, to indicate where an event occurred or to reference a diagram) without trying to dramatize or sway the jury. So, the statement is not appropriate; officers should avoid using hand movements to prove their point and focus on factual testimony.
