You don’t think it’s within their capacity to build and secure a corral outside their village?
You really don't understand do you.
The predators I am talking about can jump over 12 feet in the air. A wood fence would be easy for them to climb.
Fire and large groups of people are what keep them out of the village.
The same with the criminals. How many men would you put on guard to keep the cows safe? They are not allowed guns so they would have to stand guard with sticks. And since they will still have their day job to do how long can they go without sleep?
People do the best they can with what they have.
