"Milwaukee is an ideal drug transportation and distribution center in part because of its geographic location and multifaceted transportation infrastructure. Three types of organizations are responsible for most of the transportation and wholesale distribution of drugs in Wisconsin: Mexican drug trafficking organizations transport cocaine, marijuana, and methamphetamine; Nigerian criminal groups distribute Southeast Asian heroin; and Dominican criminal groups distribute cocaine and South American heroin. The most common means that transporters use to ship drugs into Milwaukee are private vehicles, commercial trucks, bus services, package delivery services, air parcel services or couriers on commercial flights, and railways. Organized street gangs such as the Gangster Disciples, Vice Lords, and Latin Kings control the distribution and retail sales of cocaine, heroin, and marijuana not only in Milwaukee, but also throughout the state. Violent crime associated with street gangs, while declining in some major urban areas, is increasing in suburban and rural areas of the state as these gangs expand their drug markets. The primary drug threats in Wisconsin are the availability and abuse of powdered cocaine and the subsequent conversion, distribution, and abuse of crack cocaine."
