The Bedouin people think most highly of people who show loyalty. To them loyalty does not mean that one is devoted to a country, a place, or a leader. Loyalty means being faithful to one’s family and tribe.

A man’s position among the black-tent people depends upon his ancestors, relatives, and fellow tribesmen. If they are honored, he is also honored. If they are disgraced, he too is disgraced. Therefore one carefully guards the honor of his family, his lineage, and his tribe.

Most probably new organizational forms will emerge to combat new manifestations of criminality.
