On the campaign trail Mexico’s new President Andrés Manuel López Obrador floated several possibilities to reduce crime without using law enforcement. These included granting amnesty to low-level criminals and negotiating with crime bosses.

But, Angélica Durán-Martínez argues, violence in Mexico is so pervasive that the country must consider every available option.
