An individual involved in what activity could be considered to be engaging in gang-related behavior?

Engaging in criminal acts is a key indicator of gang-related behavior. Gangs are often associated with illegal activities, which can include a range of offenses such as drug trafficking, violence, extortion, and other forms of criminal behavior. These activities serve the interests of the gang, promote its influence, and contribute to its reputation and power within the community.

In contrast, participating in community service, collecting charitable donations, or organizing public meetings are generally associated with positive, constructive community involvement. These activities do not align with the motives or behaviors typically associated with gangs, which are primarily focused on illicit gains and territorial control. Therefore, committing criminal acts is the action that definitively correlates with gang involvement.
