Street Gangs; this are gangs that usually operate in most parts of the country, and pose a significant threat cause they are made up of a very large group and control a very large geographical region. As a result, some criminal activities like drug trafficking and violence are in most cases performed by this type of gang. The threat might become magnified “as national- and regional-level street gangs migrate from urban areas to suburban and rural communities, expanding their influence in most regions and broadening their presence outside the United States to develop associations with DTOs and other criminal organizations in Mexico, Central America, and Canada”, (Curry & Spergel, 38) they can be divided into national level gangs; who might have associates in foreign countries.
They usually have thousands and thousands of members nationwide operating in multiple regions. Another category is regional-level street gangs; who distribute drugs at a wholesale level. Basically, they can be organized by hundreds to thousands members. The last category is the local street gangs; in most cases, they are referred to as neighborhood-based gangs. They usually pose considerable threat to local and federal law enforcement. In most cases, street gangs are local-level gangs operating a single. Their membership is from three to hundreds. Most of them engage in violence and criminal activities, including retail drug distribution.
Prison gangs: this group has posed serious threats particularly national-level prison gangs. They also maintain reasonable impacts on street gangs in areas that they operate. This group of gangs is highly structure criminal networks that operate “within the federal and state prison systems. Furthermore, these gangs operate in local communities through members who have been released from prison. Released members typically return to their home communities and resume their former street gang affiliations, acting as representatives of their prison gang to recruit street gang members who perform criminal acts on behalf of the prison gang” (Hagedorn, 165). They usually take the responsibility of controlling the distribution of drugs within correctional centers, and strong affect street level distribution in some communities. Just like street gangs, they are also categorized into; national-level prison gangs, regional-level prison gangs and local or state-level prison gangs.
