She said that the Philippine National Police’s Oplan Tokhang program should be stopped. This has been a practice of the police to visit drug suspects — pushers or users — to warn them and get them to surrender or just stop their illegal activities. But tokhang, on the whole, has been effective in clearing communities of the drug problem, as the drug suspects would realize they’ve been identified, and they mostly leave the area. The very term implies a peaceful approach really, as it is derived from the Visayan terms “toktok” (knock) and “hangyo” (plead).
