Stabler and Benson arrive at the residence of Peter Harrison (Nick Stahl.) Stabler announces they are the police and to open up, but Harrison asks if they have a warrant. Benson makes up a story about them having to check him out since he was injured doing court ordered service and they need to assess his injury, and Harrison opens the door, leaving the chain on. Harrison shows them his thumb, which is covered with duct tape instead of a bandage. He says he ran out of band-aids and that they know that already. He is acting clearly paranoid, as he talks about their satellite surveillance and wiretaps. Stabler makes up that Harrison must know about rule 1063 , which says that any subject of intrusive police monitoring has a right to a binding cease and desist order against the department if he so chooses and sign a DD5 form. This gets Harrison out of the apartment and down to the SVU squad. The problem is when Peter goes to leave, there is no chain on the door.
