While in Iran about 4 years ago, we (3 bike's and a car) camped out in the desert, near a small vilage.
We had a visitor at night who ran of with a helmet and a rain-suit. We chased him, but he disapeared in the vilage.
The next morning we asked some people if thay had seen anything, but they had all been deep asleep (apart from one that is).
20 minutes later the mayor, the chief of police and half the city-council showed up at our camp. Apologizing dozens of time, handing over gift,s (mostly fruight and other yummie things) and promising to find and punish the villan. We even got to tell what punishment he should receive.
So, Yes, there is crime. But most of the people are friendly, helpfull and honest.
So, if you see a guy running around in a rain-suit and a helmet...... (probably with his hand cut of)... you know he can not be trusted
But I am sorry for your bad experiances. I hope it is the last.
