Drug-criminals take advantage of commutation by passing over the insider’s information bought from ‘Ya-Dang’. Cops and prosecutors, on the other hand, make performances by using the information. There is a triangle in Korean drug-crime scene: police, prosecutors and the game changer, ‘Ya-Dang’.
Unfortunately the movie Yadang: The Snitch is not yet available on HBO Max.
