More than 8,000 people have reportedly been killed over drug-related offenses since Duterte took office last year. Numerous rights groups have been critical of the killings and have spoken out against the current administration. Early in March Human Rights Watch [advocacy website] released a report that accused the police of falsifying evidence [JURIST report] in relation to the alleged police killings of citizens. This policy of sanctioned killings has been part of Duterte's rhetoric since his time as mayor of Davao City. In December a UN Human rights chief called for a murder investigation [JURIST report] after Duterte admitted to killing people in his role as mayor.
