During a speech in Puerto Princesa City in Palawan, the president said that Pangilinan was the "most stupid" of lawyers for authoring Republic Act 9344 of the Juvenile Justice and Welfare Act of 2006, which exempted minors below 15 years old from criminal liability.
"If you do not have anything to say except to criticize like Pangilinan, well, I'm sorry, pero shut up... ikaw yung abogadong alam kong pinaka-bobo sa lahat," Duterte declared.
While he had no intention of "destroying" his "friend" Pangilinan, the president could not help but be appalled by a law which allegedly allowed young criminals to run free regardless of the gravity of the offense.
"Pangilinan 'yan, mag-isip lang kayo noong hindi panahon sa batas ni Pangilinan at ngayon ang nangyari," Duterte said. "Hindi mo talaga ma-detain ang bata whatever the crime may be. It could even be genocide. Walang sasagutin."
Sought for his reaction, Pangilinan suggested that the President needed to focus on the country's problems.
"Instead of resorting to insulting his critics it would be better if Malacañang focuses on bringing down the prices of basic goods and on going after the big time drug syndicates running circles around the BOC and the PDEA," the senator told GMA News Online in a text message.
