Colombian President Gustavo Petro.

Last week, Colombian President Gustavo Petro threatened to call for a constitutional convention, reopened peace talks with a notorious criminal group and canceled a cease-fire with a dissident FARC faction. Announcements like these would normally create months’ worth of media coverage. Under Petro, they have become almost uneventful.

The suspension of a Brazilian judge last month as part of an investigation into his links with an organized crime group did not make headlines. But it is a worrying sign of the ever-growing influence of the country’s main drug-trafficking organizations, which have steadily accumulated wealth and power in recent years.
