Welcome to The Mid-Atlantic Regional Gang Investigators Network Website
The Board of Directors and its members would like to welcome you to the Mid-Atlantic Regional Gang Investigators Network, formally known as Washington/Baltimore Metropolitan Area Regional Gang Investigators Network. MARGIN is an organization consisting of federal, state and local law enforcement/criminal justice professionals, representing agencies from throughout Maryland, Virginia, Washington, D.C. The primary goal of the network is to enhance officer safety by providing relevant gang information to law enforcement officers and for the overall public safety.
In 1992, an informal group of gang investigators representing seven law enforcement agencies from throughout the Washington Metropolitan area started exchanging information. The investigators soon recognized that gangs were proliferating throughout the area, that working street gangs was complex, and that the need to share gang information was mandatory. The investigators named the group the Washington/Baltimore Metropolitan Area Regional Gang Investigators Network (MARGIN) and met on a monthly basis to exchange information on current investigations, gang structure, membership, the crime associated with their activities, and new trends and patterns. Monthly meetings were, and are today, hosted by the various participating member agencies. MARGIN was renamed as the Mid-Atlantic Regional Gang Investigators Network to better describe the Network's geographical area of concern.
