He just kill all people who are involved in drug. You don't solve problems just to murder all who don't fit you ideally country in his eyes. A country without drugs don't exist it will always be part of the world.
i think base on my own understanding, there are much more victims of drug addicts and pushers in the philippines, and the president didnt actually order the murder of the drug addicts. don't base it always in mainstream media.. learn to research too
