"The 55-year long Colombian conflict with the FARC guerrilla movement ended in 2016 with the signing of a peace agreement, which resulted in a substantial reduction in the number of victims of socio-political violence. Paradoxically, this did not improve security for journalists, who were targeted: one was killed, another suffered sexual abuse, and 262 received threats. In a qualitative case study, we content analyzed 592 tweets in order to document how threats from a political powerholder contributed to the formation of networks engaging in verbal violence on Twitter. Results showed that attacks on freedom of the press originated from a legitimate actor, caused an extremely polarized discussion among citizens who took sides, and provoked further threats and accusations. Conciliatory positions were hard to find." (Abstract)
