A Quezon City SWAT officer holds a shotgun during a "knock and plead" operation, as part of President Rodrigo Duterte's war on drugs. Police officers knock on doors to ask drug users to voluntarily surrender.

An armed officer accompanies a "knock and plead" operation in the Bangaray Labis slum in Quezon City.

Officers and the neighborhood "captain" Leny Glivano talk to a resident during a late night visit.

The "knock and plead" operations involve going to the homes of those suspected of using methamphetamine -- and inviting those inside to accompany the police to the local town hall.

At the hall, those rounded up sit around a starkly lit room, waiting to be registered as drug users. They are interviewed by police about local dealers.

Hands raised, the detainees recite a pledge that affirms that their surrender is voluntary. They promise to "undertake to stop all" drug-related activities.

Mug shots are taken, and those surrendering are required to provide a urine sample for drug testing.

The detainees are also fingerprinted -- but the Philippines National Police Chief, Ronald Dela Rosa, tells CNN that the surrenders are not arrests.
