I've currently live and have lived in Davao on and off since 1994 where Durterte had been mayor for the past decades. When I first arrived in Davao, there were no street lights in the city, nearly no cars, and there were still bombings such as at the main church.
The city has come a long way and is much improved under Durterte. Drugs were destroying the youth and the city. I personally experienced suffering from ill effects of drugs when my former family members in Davao became addicted to drugs.
In 2003 I personally met someone who claimed to be a member of the Davao Death Squad and he showed me his gun. He was very amicable and he explained that offenders were given many warnings and they were only killed if they refused to reform or leave Davao (they were given this choice).
I have personally suffered from Durterte's heavy hand when he recently banned night time driving in Davao for anyone blind in one eye. I found a way around this, but it was a major hassle and now with him as President I don't think my rights will be respected here so I probably want to leave the Philippines which has become my home for half of my life.
The economic and population situation in Asia is very extreme and the officials have to be pragmatic. I think Durterte is necessary for the Philippines to avoid sinking into a hell again, but there is a cost in terms of freedoms and rights. I haven't yet decided if there is another place I'd rather live.
