For around six years I lived in Davao city on the Island of Mindanao here in the Philippines. The Island has a bad reputation of fighting between government forces and the Islamic militants. However living in Davao City is easiest one of the safest place sin the whole of the Philippines. The mayor has managed to clean up the city.
Of course he has his enemies, but he has understood that money only flows in to a city that is safe and able to have foreign visitors stay safe. He has achieved this. Many take a bleak view of the way he managed to do this, but at the end of the day Davao is a much safer city and I a place that any foreigner can walk around at night without feeling too worried about any criminal activities happening against them.
