Actually all those things on Oahu when I lived there a decade ago, add that you couldn't go to many beaches outside the tourist areas because they're controlled by the meth dealers who squat there, but like I said I'm sure to a lesser degree than you experienced. But I was actually more referring to the whole inertia thing, for example took nearly 3 months to close a house purchase which had no issues and which everyone wanted done in a week. Every house I've subsequently bought and sold in the rest of the country has been 2 weeks max, 1 week in one case. Again, just a taste of what you're describing but enough that I can completely feel what you're talking about.
Don´t read too much into what Blueraincap writes about safety in Spain, especially if he is comparing to other european countries rather than Singapore :

https://en.wikipedia.org/wiki/Crime_in_Spain
Spain fares pretty well security wise, although there are pickpockets and houses get broken in.
It sure depends on where one lives, I definetely don`t hang out in night buses but lived in Germany and Switzerland (was in Zurich when they closed the Letten, over 20 years ago)while younger and close to broke, there are or at least were plenty of hard drugs and junkies out in the street, it was standard in Frankfurt to see drug addicts smoke crack openly in the street or even sitting in a bus stop. You probably wouldn´t feel most confortable hanging out in St Georg in Hamburg or previously around the Letten or Langstrasse in Zurich, yet BRC would purposedly go there and summarise the whole country based on that experience (it`s like Saint denis in Paris, no half well off parisian would set a foot there, but he managed to visit it)
Nowadays when I travel to Germany I do not see this stuff, yet a couple of years ago I drove close to the Red light district in Frankfurt, see how it felt after all those years, and had to U turn and drive away promptly, a bit freaked out. There are many areas in Madrid, even downtown, where it actually gets more expensive, where you can stay largely away of the riff raf.
I´m reading more about the admin processes in Spain, and it is far from a walk in the park even for EU citizens (I managed to get a house, bank acct, public and private insurance, NIE, residence permit, new car, phone number and internet in a few weeks still)- but kids and Mrs docs are not ready, Mrs` permit and insurance actually appear far from ready.
Would need to read an update but crime in Portugal is supposed to be lower than in Spain and most of Europe.
