Does an officer's training and experience influence probable cause determinations?

• A. No
• B. Only if investigators
• C. Yes
• D. Only if there is written policy

Answer: (C)

Probable cause determinations are informed judgments based on the facts and circumstances an officer observes or learns about. Training provides the foundational knowledge of what kinds of facts are legally significant and how to recognize indicators that fit the standard. Experience adds the ability to assess credibility, interpret ambiguous information, and weigh the totality of the circumstances in a real-world setting. Together, training and experience shape how an officer decides whether the facts amount to probable cause, rather than relying on hunches. While written policy or investigators’ procedures explain steps to take, they do not replace the influence of an officer’s training and experience on the determination itself.
