I come from a tribal culture that believed in having no “police”. 

There was a code of ethics called the Xabze. 

The Adyghe Xabze, a traditional code of conduct among the Circassian people, was primarily enforced through social norms and cultural practices rather than through formal legal structures. It emphasized values such as hospitality, honor, bravery, and respect for elders. Violations were typically addressed through community consensus, with social ostracism or public shaming being common consequences for those who broke the code. Additionally, elders and leaders within the community often played a role in mediating disputes and ensuring adherence to the Xabze.
