Which of the following is NOT a requirement before interviewing a suspect according to best practices?

The correct answer highlights that ensuring the presence of legal counsel is not a strict requirement before interviewing a suspect, according to best practices. While it is indeed advisable and often legally necessary in certain contexts to allow a suspect to have an attorney present, particularly in custodial situations, there is no absolute requirement to have legal counsel present before conducting an interview in all circumstances.

On the other hand, informing suspects of their rights, providing clear information about the interview process, and conducting the interview in a private setting are all integral aspects of ethical interviewing practices. Informing suspects of their rights protects their legal interests and ensures they understand the implications of the interview. Clear communication about the interview process helps in gaining cooperation and understanding from the suspect, while a private setting aids in creating an environment conducive to open dialogue and minimizes external distractions.
