Filipino police, military and vigilantes have killed more than 400 people in a crackdown against drug crime since President Rodrigo Duterte took office a month ago. Human rights groups say many of those killed have been summarily shot or had nothing to do with the drug trade. More than 100,000 people have turned themselves in to police for drug offenses to avoid the prospect of a violent arrest. Prior to his election, Duterte admitted to his role in death squads, joked about the gang rape of an Australian missionary and pledged to kill tens of thousands of people.
