Manila: Police in the Philippines on Monday resumed President Rodrigo Duterte's war on drugs, making visits to the homes of users and dealers to convince them to surrender, but the national police chief declined to guarantee that blood would not be shed.
The programme of visits, known as "Oplan Tokhang", made a comeback with an assurance from police chief Ronaldo dela Rosa that it should be free of violence if offenders agreed to go quietly and did not resist.
But he could not promise a "foolproof anti-drug campaign that would be bloodless", Dela Rosa added, as the police were "not dealing with people who are in their proper state of mind".
In the dialect of Duterte's southern hometown of Davao, "Tokhang" is a combination of the words "knock" and "plead".
Besides the visits, police have also run so-called "buy-bust" or sting operations and raided suspected drug dens and illicit laboratories.
In many of these operations, say rights activists, suspects did not get the chance to surrender, but were executed in cold blood instead. But police insist suspects died because they violently resisted arrest.
Nearly 4,000 drug suspects have died in gun battles with police since June 2016, when Duterte came to power. The government lost 85 police and soldiers in the drugs war, police data show.
More than 1.2 million people had also turned themselves in after the home visits.
Duterte has stopped police anti-drugs operations twice due to questions over the conduct of the force.
To ensure transparency, Dela Rosa invited human rights advocates, priests and the media to join the relaunched programme of home visits.
The police officers involved would also undergo a vetting process to weed out "rogue" officers, said Dela Rosa, adding that past abuses had involved the police seeking bribes to drop the names of people from the lists they compiled.
"We are certainly hoping that it will be less controversial, because controversy will only blur the real intention, which is really the fight against dangerous drugs," Harry Roque, Duterte's spokesman, told a regular media briefing.
