President Duterte, whose sincerity you can almost tangibly feel and smell when he speaks, has always vowed to uphold due process despite his penchant for the I will kill you! line, and that suspects will be killed only if they resist arrest, and fight it out with the arresting police officers. PNP chief Ronald Dela Rosa has consistently echoed Duterte’s pronouncement.
I don't doubt the president, but this unbridled killings of arrestees despite the obvious improbability of resistance knowing they would be killed suggest that rogue members of the police force--yes they still exist even among those who actively take part in this war on drugs, or at least make it look like it; even the president has expressed this view--are putting one over Duterte and Dela Rosa by silencing their erstwhile cohorts to keep them from snitching on them and their bosses, or standing witness against them in court using the very program (double barrel and tokhang) that the president has designed to net them.
The president must neither tire out, nor take these extra-judicial killings for granted. He has to put Dela Rosa to task in investigating these dubious custodial killings. We know there are legitimate kills, but a thousand or so deaths from a template “nanlaban” must merit a deep and resolute investigation into their circumstances. The same goes to the now ubiquitous riding-in-tandem shootings of suspected drug offenders. It does not help that Dela Rosa, in the early goings, expressed his favour for these summary or extra-judicial killings treating them as a boon to their campaign, although he has since repeatedly clarified that he, like the president, hated and would not tolerate extra-judicial killings. His actions, however, continue to play catch-up with his declarations.
