Step-by-step explanation:
The question pertains to the appropriate protocol for members (presumably law enforcement) to contact or approach a sexual assault suspect without the involvement of a Specialized Assault Unit (SAU). The correct procedure would be B) After obtaining a search warrant. Law enforcement procedures emphasize respecting individuals' constitutional rights and ensuring that any evidence collected is admissible in court. Approaching a suspect without the necessary legal documentation such as a search warrant may jeopardize the case and violate the suspect's rights. It's critical that law enforcement officials follow due process, which means obtaining a search warrant from a judge based on probable cause before engaging in any search or seizure at a suspect's address.
