When organizing a corporeal lineup, what is the first action you should take?

  1. Locating persons with similar physical descriptions

  2. Asking your supervisor what is and is not appropriate

  3. Determining if the lineup is appropriate based on witnesses

  4. Informing the public about the lineup procedure

The correct answer is: Determining if the lineup is appropriate based on witnesses

When organizing a corporeal lineup, determining if the lineup is appropriate based on witnesses is the critical first step. This action ensures that the lineup will be relevant and useful in the investigative process. It is essential to consider the accounts and descriptions provided by witnesses, as their perspectives can guide how the lineup is constructed. This assessment helps to establish whether the lineup is likely to yield valuable identification or whether it might introduce issues such as suggestiveness or bias, which would compromise its effectiveness. Focusing on witness input and the relevance of the lineup ensures that the procedure aligns with the needs of the investigation and increases the likelihood of a reliable identification. This approach is crucial for upholding the integrity of the criminal justice process and protecting the rights of all individuals involved.
