The Boston police department's drug units are focusing on violent drug dealers in an attempt to cut down violence between them. Criminals with a history of violence or firearms are being focused on, the police are concerned with violence between rival drug gangs.
The drug units use undercover officers who rely on numerous street informants to get information on who's dealing drugs. The idea is that if the most dangerous criminals can be taken off the street it will reduce violence against the community and other rival dealers. Some detectives believe the economy has led people who have never dealt drugs before into the business.
