Tanauan City, Batangas Mayor Antonio Halili, who has initiated the walk of shame campaign for suspected drug pushers and users, was shot dead by an unidentified gunman during a flag raising ceremony in his city Monday, Philstar Global reports. Halili is the latest local executive killed since President Rodrigo Duterte assumed power in July 2016. Rappler tallies at least 4 vice mayors and 9 mayors slain based on media reports between July 2016 and July 2018. With the exception of Albuera, Leyte Mayor Rolando Espinosa Sr who was shot dead while detained, all were killed while holding office. Halili, who paraded drug suspects through the streets, was known for his hardline position on drugs. But he was also accused of protecting drug traffickers – something he denied. The shooter was able to escape, and no suspects have been identified yet, BBC reports.
