The Philippine National Police (PNP) said Tuesday it will implement stricter security protocols and increased police deployment ahead of the planned anti-corruption protest on November 30, to prevent a repeat of the violent clashes that occurred in Manila last September.

Acting PNP Chief Lt. Gen. Jose Melencio Nartatez Jr. said the police have already incorporated lessons learned from the September 21 rally, where several young protesters allegedly used debris and incendiary devices against security forces.

“The PNP reaffirms its commitment to maintain peace and order and to secure demonstrations conducted by the public,” Nartatez said in a statement.

“We have learned from the September 21 incident that turned violent, and I assure our kababayan that we are ready to respond to any eventuality during the November 30 protest actions,” he added.

Nartatez confirmed that more police officers will be deployed during the demonstrations, with instructions to exercise maximum tolerance but zero tolerance for violence or destruction, including the setting of fires or throwing of projectiles.

He emphasized the importance of coordination with protest organizers to ensure that participants can express their grievances peacefully without endangering public safety.

The PNP’s security plan focuses on three key priorities:

1. Close monitoring of protest groups;

2. Reinforcement of security barriers and surveillance systems, in coordination with local government units (LGUs); and

3. Additional deployment of security personnel in critical areas.

"We continuously monitor personalities and groups that may attempt to sow chaos. That’s why we have already filed cases,” Nartatez said.

The September 21 protest was initially peaceful in major areas such as Luneta Park in Manila and the People Power Monument in Quezon City, until violence erupted near Ayala Bridge and Mendiola, where some protesters — including minors — clashed with police and attempted to storm Malacañang Palace.

The incident left nearly 100 police officers and several protesters injured.

The Criminal Investigation and Detection Group (CIDG) said on Monday that 97 individuals have already been charged before the Department of Justice for their involvement.

CIDG Director Maj. Gen. Robert Morico II said the charges include inciting to sedition, conspiracy and proposal to commit sedition, and sedition under the Revised Penal Code.

“The investigation is ongoing, and in the next few days, we will be filing additional cases against the instigators and those behind the violent incidents in Recto and Mendiola,” Morico said.
