orders D'Angelo killed, with the murder staged to look like a suicide. Avon is unaware of Stringer's duplicity and mourns the loss of his nephew. Stringer also struggles, having been cut off by Avon's drug suppliers in New York and left with increasingly poor-quality product. He again goes behind Avon's back, giving up half of Avon's most prized territory to a rival named Proposition Joe in exchange for a share of his supply, which is revealed to be coming from the Greek. Avon, unaware of the arrangement, assumes that Joe and other dealers are moving into his territory simply because the Barksdale organization has too few enforcers. He uses his New York connections to hire a feared assassin named Brother Mouzone. Stringer deals with this by tricking his old adversary Omar into believing that Mouzone was responsible for the vicious killing of his partner in their feud in season one. Seeking revenge, Omar shoots Mouzone but, realizing Stringer has lied to him, calls 9-1-1. Mouzone recovers and leaves Baltimore, and Stringer (now with Avon's consent) is able to continue his arrangement with Proposition Joe. Season 3 In the third season, the focus returns to the street and the Barksdale organization. The scope is expanded to include the city's political scene. A new subplot is introduced to explore the potential positive effects of de facto "legalizing" the illegal drug trade, and incidentally prostitution, within the limited boundaries of a few uninhabited city blocks—referred to as Hamsterdam. The posited benefits, as in Amsterdam and other European cities, are reduced street crime city-wide and increased outreach of health and social services to vulnerable people. These are continuations of stories hinted at earlier. The demolition of the residential towers that had served as the Barksdale organization's prime territory pushes their dealers back out onto the streets of Baltimore. Stringer Bell continues his reform of the organization by cooperating with other drug lords, sharing with one another territory, product and profits. Stringer's proposal is met with a curt refusal from Marlo Stanfield, leader of a new, growing crew. Against Stringer's advice, Avon decides to take Marlo's territory by force and the two gangs become embroiled in a bitter turf war with multiple deaths. Omar Little continues to rob the Barksdale organization wherever possible. Working with his new boyfriend Dante and two women, he is once more a serious problem. The violence related to the drug
