McNulty meets with Carver to discuss his joining the homeless murder detail. Carver asks why him over a Sergeant from the district where the murders occurred. McNulty admits there is a hitch and closes the door. Carver tells McNulty that he does not want him or any of his people to get burned. McNulty explains that he is using resources assigned to the homeless detail to assist Lester Freamon in following up a new lead on Stanfield. Carver guesses that Freamon is actually running a wiretap and McNulty denies any knowledge. Carver reveals that he gave Freamon the cell phone number Stanfield is using and McNulty continues to deny involvement. Carver asks about the paperwork and McNulty offers to handle that aspect and asks Carver to send him people willing to work. Carver nods his assent and McNulty goes to leave but Carver stops him to ask about cars and McNulty tells him the department has an account with a hire firm.
