I have a test where I am given the following article, what is an answer for the question: Who does the man who volunteers to infiltrate the gang shoot? ?

The story begins in Harlem, 1986, and Nino Brown and his gang, the Cash Money Brothers, become the dominant drug ring in New York City once crack cocaine is introduced to the streets. His gang consists of his best friend, Gee Money; enforcer Duh Duh Duh Man; gun moll Keisha; Nino's girlfriend, Selina, and her tech-savvy cousin, Kareem. Nino converts the Carter, an apartment complex, into a crack house. Gee Money and Keisha kill rival Fat Smitty, the CMB throws out the tenants, and Nino forces the landlord out onto the streets naked. Meanwhile, Undercover detective Scotty Appleton attempts to make a deal with stick-up kid Pookie, but Pookie runs off with the money. Scotty chases Pookie and shoots him in the leg, but the police let him go. Nino's gang successfully run the streets of Harlem over the next three years.
When Det. Stone comes under pressure, Scotty volunteers to infiltrate Nino's gang and is partnered with loose-cannon Nick Peretti. Elsewhere, mobster Frankie Needles attempts to collect taxes from Nino, who refuses to pay. While Scotty and Nick spy on Nino and his gang as they hand out Thanksgiving turkeys to the poor, Scotty spots Pookie, now a crack addict, as Pookie beats his junkie girlfriend. Instead of arresting him, Scotty puts Pookie in rehab, and, later, Pookie offers to help bring down Nino. Against his better judgment and the disapproval of Stone and Peretti, Scotty recruits Pookie as an informant in the Carter.
