The subject of known of Iranian hospitality could be the key point for the mental security of anybody visiting Iran.

Any need automatically would be helped by the people on the street. As the way that the tourist is not only tourist but they are the guest as well this is the best security that everyone would have.  In Iran by traditional the security of the people is practiced by the people them self .many problems are solved by within the people rather than the police.
