Following is a summary of an International Business Times article:
Duterte said in a recent press conference: “Most of you are clean, but do not ever expect that journalists are all clean. They take sides. Just because you are a journalist you are not exempted from assassination if you’re a son of a bitch.”
In the two months since president-elect of the Philippines Rodrigo Duterte was elected from the beginning of May to the end of June, over 60 people have been killed by police or roving gangs who accused the victims of being drug dealers, with the killers often leaving hand written notes on the corpses.
When Duterte was previously asked what will happen to criminals once he becomes President, he said “The 1,000 [I allegedly killed] will become 100,000. That will fatten the fish in Manila Bay. I will dump their bodies there.”
The following link mentions that many of the killings are likely being committed by police who have been in league with the drug dealers and are trying to cover their tracks.
