THE tanim-bala (bullet planting) modus at the Ninoy Aquino International Airport (NAIA) that is being denied by airport authorities might just be the push Davao City Mayor Rodrigo Duterte needs to finally heed the call to run for president.

"The government has failed to protect the welfare of its people," Duterte said, adding that this might change his current decision to run. "I said that I don't have the ambition to be a president pero kung ing-ana ilang padagan puro daug-daug, binuang na na (if the way they run government is to oppress the people, that’s crazy)," Duterte said.

Duterte made an appeal to President Benigno C. Aquino III last Monday to make drastic moves to solve the problem, saying that he never asked for any favor in exchange for his support, except this one.

Duterte supported the Aquino-Roxas tandem in the 2010 elections.

He also said that the President must relieve all officials and employees connected to the Civil Aviation Authority of the Philippines (CAAP) and the aviation command including also the porter services and drivers.

Duterte said only a conspiracy with porters, drivers, and airport authorities can create such a situation.

It’s tragic enough that passengers here are detained for these planted bullets, much more if they escape detection and are caught instead in airports abroad.

Still, Duterte said he has not fully made up his mind.

"Look, December 10 is the deadline, why don’t you just wait for it," he said.

He added that if ever he runs, it’s his decision and not because PDP-Laban urged him to.

"Wait, just wait," Duterte said.
