You have probably heard of the notorious hermanos Fernandez gang and their activities up and down the costa.
They are Columbian and I needed a job, so ended up as a delivery driver for them. Stupidly I nicked off work early one night to watch the England match, and falsified my timesheet. That was it, you dont cross los Fernandez and get away with it! 
Next thing I know i'm tied up in a warehouse somewhere near La Linea with crocodile clips attached to my knackers and wired up to the national grid. Gracias a dios - it had been raining heavily and there was a power cut that night, so I escaped with just a beating. Let that be a warning to you Dane, there are some heavy people out there.
Sleep tight.
The bit about the power cuts is true though.
I do not know a soul in my area that feels the need to instal security bars, security gates, employ guard dogs etc. You never see a house along the coast in Spain that doesn't look like Fort Knox. If crime is so low, perhaps you could explain why they all have to resort to these security measures. On a personal level, whilst I don't live in a large town in UK, I feel ten times safer here than I do in Spain. My neighbours lived here for many years without any problems, in Spain they've had their solar panels nicked and the car broken into. Welcome to Spain! But nice to see you're impressed with the Spanish police!
Its the same with every subject now on A.com, some posters seem to have to keep convincing themselves that they made the right decision to leave yUK and everything about their new country of residence is better than their old home.
