MANILA- Most Filipinos believe that some drug suspects were killed even after they surrendered themselves to authorities, results of a Social Weather Survey showed.

A total of 63 percent of Filipinos agreed to the statement: “May mga suspect sa ilegal na bentahan ng droga na sumuko na, pero pinatay pa."

(There are suspects in the illegal drug trade who already surrendered, yet were still killed)

Of the 63 percent, 31 percent strongly agreed while 32 percent somewhat agreed. Meanwhile, 17 percent were undecided, 11 percent somewhat disagreed, and 9 percent strongly disagreed.

Most of those who agreed came from Metro Manila at 75 percent followed by Mindanao and Balance Luzon at 63 percent and Visayas at 53 percent.

The new poll results come days after another SWS survey claimed that more than half (54 percent) of Filipinos expressed doubt that many of those killed in anti-drug operations really fought it out with cops.

Police under the term of President Rodrigo Duterte, have been heavily criticized several times for doubts on the conduct of their anti-drug operations particularly "Oplan Tokhang," where cops knock at the doors of suspected drug users and peddlers to ask them to surrender.

The administration has several times defended the campaign, saying drug suspects killed in legitimate police operations had put up violent resistance.

Latest police estimates placed the number of drug suspects slain in legitimate police operations at 3,800. Human rights groups meanwhile placed the figure at 13,000, which the administration has described as overblown.

Respondents to the survey were also asked whether they knew of someone who was falsely summoned for Oplan Tokhang.

Results showed that most Filipinos, at 83 percent, did not know anyone falsely summoned for Oplan Tokhang and that only 17 percent did.

Most of those who knew someone who was summoned for Oplan Tokhnag despite not being linked to illegal drugs, were from Metro Manila at 22 percent followed by Visayas at 18 percent, and Balance Luzon and Mindanao at 16 percent.

The survey, which was conduced from June 23-26, used face-to-face interviews with 1,200 adults aged 18 years old and above nationwide, 300 each in Metro Manila, Balance Luzon, Visayas, and Mindanao.

It has a sampling error margins of ±3 percent for national percentages, and ±6 percent each for Metro Manila, Balance Luzon, Visayas and Mindanao.
