A still-unfolding scandal in Colombia is revealing that the government’s intelligence agency not only spied upon major players in Colombia’s democracy—from Supreme Court and Constitutional Court judges to presidential candidates, from journalists and publishers to human rights defenders, from international organizations to U.S. and European human rights groups—but also carried out dirty tricks, and even death threats, to undermine their legitimate, democratic activities. And it may have carried out its illegal surveillance with orders from top presidential advisors. The next Colombian administration must be challenged to fully reform the nation’s intelligence services to put an end to these authoritarian practices.
