MANILA - Senator Panfilo Lacson believes the Senate should not get in the way of President Rodrigo Duterte's campaign against illegal drugs.

This, as Senator Leila de Lima pushes for an inquiry on alleged summary killings of drug suspects.

"Bakit mo kailangang sirain ang momentum? Ang dami nang sumu-surrender," said Lacson.

He said a Senate inquiry may only create a "spectacle" out of the legislative body which can instead focus on other matters.

Lacson believes either the Commission on Human Rights (CHR) or the Department of Justice (DOJ) should be tasked to investigate cases and not the Senate.

Lacson, however, criticized Solicitor General Jose Calida for his statement against the possible Senate inquiry. "His statement was uncalled for," the senator said.

While he recognizes there might be cases of summary killings perpetrated by policemen, Lacson believes individual policemen, and not the whole police force led by Director General Ronald "Bato" Dela Rosa, should be investigated by the proper government agencies.

Lacson revealed that Dela Rosa initially sought his advice as a former police chief and that they constantly communicate through text messages.

The senator, meanwhile, also said that he has already filed his bills at the Senate which include the death penalty bill seeking capital punishment not just for drug-related cases but other heinous crimes as well.
