What is the location requirement for a photographic spread?

The correct answer highlights the flexibility of the location where a photographic spread can take place. Specifically, it can be conducted anywhere, provided that the primary objective is the identification of a suspect. This means that the setting does not have to be confined to formal locations such as a police station or laboratory. Instead, the focus is on ensuring that witnesses or victims can view the photographs in a setting that is convenient and suitable for them, which may often lead to more effective identifications.

This approach aligns with best practices in witness identification processes, where the aim is to minimize stress and promote clarity during the identification procedure. The other options suggest unnecessarily restrictive or formal conditions that do not account for the practical considerations of conducting a photographic spread. For instance, it is not mandatory for the identification to take place in a police station or specific legal environment, nor is it required for a suspect's attorney to be present in every situation.
