In partnership with the City of Medellín and community officials, EDI researchers co-designed a program of intensified government outreach and service delivery to test the impact of increased municipal governance on the roles and legitimacy of local gangs and the state. To design the program, researchers conducted interviews with more than 30 members of 19 criminal organizations over two years.
