"Do not bullshit with me but do your duty, I will die for you," Duterte said.
In his speech after the oath-taking ceremony of PNP chief Ronald "Bato" Dela Rosa, Duterte said that he knows that some police officials are involved in illegal activities.
"I know your life story. I know how you handle your work and I know how good you are.
But I also know sometimes you can become a bad boy in the organization so beginning from now, I will not tolerate, zero tolerance for abuses committed by the law enforcement agencies including the National Bureau of Investigation," Duterte said.
Duterte said that he will be harsh but he reminded the PNP about the fundamentals of shooting criminals following issues of extrajudicial killings.
The president added that he will provide the police force with funds and weapons in fighting criminality, particularly illegal drugs.
Duterte stressed that it was not only a campaign slogan when he promised to raise the salaries of the police and the military.
"We might not be able to stop it on time (within) six months but certainly six months and one day matapos na sana lahat. Tutal tama 'yung bayad ko sa inyo," Duterte said.
