Pape, accompanied by seven local police officers, executed a search warrant at the defendant's apartment in Lima, Ohio. The basis for the warrant, which authorized a search for evidence of child pornography, was information Agent *778 Schulte had obtained from F.B.I. agents in Oklahoma. That information provided the probable cause for the search warrant.
After the agents had knocked, the defendant and his roommate came to the door. They were asked to wait outside during the search. The defendant was not told that he was under arrest; nor was he handcuffed. He was not told he had to staybut he also was not told that he was free to leave.
Without reciting the Miranda warnings or securing a waiver of the rights referenced in the warnings, Agent Pape questioned thedefendant. He told the him the F.B.I. was there to execute a search warrant on his computer. He also told the defendant there was cause to believe he had child pornography on his computer because its IP address belonged to him. He asked the defendant if there could be child pornography on his computer.
The defendant acknowledged that he had a computer and that it contained images of child pornography.
Agent Pape is a Bureau polygraph examiner. At some point he told the defendant that he could, if he wished, take a polygraph examination. He explained that part of his role was to make sure that people with child pornography have not been molesting children.
Agent Pape said asking persons to take a polygraph examination was part of child pornography investigations,
