Which of the following best describes a gang?

A gang is typically characterized as a group of individuals who adopt an organization that often serves specific interests, which may include criminal activities. This definition highlights the structured nature and collective identity that gangs often possess, distinguishing them from more benign or altruistic group formations.

When considering the other options, they describe entities that do not align with the traditional conception of a gang. The first option focusing on community service suggests goodwill and social responsibility, rather than the often illicit activities associated with gangs. The third option describes a formal network of political activists, which implies political legitimacy and community engagement, characteristics distinct from gang behavior. Lastly, the description of a non-profit organization aimed at youth development emphasizes a positive and constructive mission, contrasting with the typically negative implications of gang involvement. Thus, the correct response accurately captures the essence of what defines a gang in the context of law enforcement and social structures.
