The burden of proof that problems are being solved is on you.
Police assertions that most violent crime in the Philippines is drug-induced/related wasn't even supported by their own data in 2016! Where's the data that shows illegal drug flows are actually being reduced and that such reductions are affecting crime rates? Where are the 'big fish' (ranking police officers, big businessmen and politicians) that were promised to be arrested/imprisoned/otherwise neutralised in 2016? Those who have been killed are either small-fry, cases of mistaken identity, or innocent bystanders.
What do you know? I've studied this. The fact that you believe that moral insight can somehow be produced from data about the status quo tells me that you haven't.
