Families of alleged drugs suspects killed by Philippine police petitioned the Supreme Court on Thursday to force police to disclose evidence linking them to narcotics, in the first legal challenge to President Rodrigo Duterte’s war on drugs. Lawyers representing families of four men killed in a run-down Manila neighbourhood in August, and one survivor, urged the top court to allow scrutiny of police operations because the official accounts were “sheer incongruity” and read like film plots “from bygone days of Filipino cinema”.
