The problem I have with that is that police officers and self appointed "deputies" become law enforcement, jury, judge and executioner in one person. No hard evidence needed. What happened to the right of a fair trial (if there was such a thing in the Philippines)? How are innocent supposed to defend themselves from wrong accusations if being accused already gets you a bullet to the head? How is made sure that no one is using the whole mess to get rid of unwanted business competition, critics etc?
What's going on there has nothing to do with a nation of law.
