The key point in this case is that guy called the police, because Circuit City employees were unlawfully detaining him. Upon the cops arrival, the police officer cut the guy off as he was explaining the situation & mentally moved him from the "complainant" category to the "suspect" category. He gave the purchases to the store employees to go through & instantly began "processing" this guy by demanding ID.
