In Barker and Carter's typology of lies, accepted lies are:

• A. Those That Occur in Court, for the Purpose of Securing a Conviction
• B. Used to Control a Violent or Dangerous Person
• C. Those Used During Undercover Investigations
• D. Never Acceptable in Police Work

Answer: (C)

Deception in police work can be viewed through a framework that weighs when lies are ethically permissible versus unacceptable. In Barker and Carter’s typology, certain uses of deception are considered accepted because they enable legitimate investigative ends that cannot be reached otherwise, and they are bounded by rules, oversight, and legal safeguards. Lies used during undercover investigations fall into this accepted category because they allow officers to investigate crimes from inside a criminal environment—posing as someone they’re not or engaging in actions that reveal how crimes unfold—without always resorting to more coercive or harmful tactics. The idea is to balance the public interest in solving crimes with the need to protect rights and prevent harm, relying on proper procedures to minimize risk and avoid entrapment. By contrast, misleading a court to secure a conviction crosses into fraud against the justice system, which is not acceptable; deception aimed at controlling a violent or dangerous person can raise substantial ethical and safety concerns; and the notion that deception is never acceptable in police work is contradicted by the acknowledged use of undercover methods. Therefore, the category that fits Barker and Carter’s accepted lies is those used during undercover investigations.
