Which type of interpreter should you avoid using?

• A. A bilingual officer without certification
• B. A Language Line interpreter
• C. A certified interpreter
• D. A family member or friend

Answer: (D)

Interpreting in law enforcement hinges on accuracy, confidentiality, and impartiality. A family member or friend should be avoided because they lack formal training and may bring personal biases or emotions that color the translation, plus they could inappropriately handle sensitive information, risking rights and the integrity of the investigation. Professional options like a Language Line interpreter or a certified interpreter provide trained linguists who understand legal terminology, follow standard protocols, and uphold strict confidentiality. A bilingual officer without certification isn’t ideal due to potential gaps in legal terminology and ethics training, which can lead to miscommunication. The safest and most reliable choice is to use a certified interpreter or a reputable interpretation service to ensure accurate, complete, and unbiased translation while protecting all rights involved.
