A simple solution: clone Chuck Norris.
Apart from the obvious benefits and inherent rightness of simply cloning Chuck in general, what feral teen on their right mind would cause trouble when Chuck’s patrolling the streets?
Think about it. A14-year-old hoodie intends to spend the evening drinking cider and shouting at passers-by. Would he even attempt this if Chuck was in the city? Of course not. Chuck will take no nonsense from hoodies. In fact, there is no such thing as the theory of evolution full stop. There are those species Chuck allows to live. The rest die.
If cloning Chuck gets too expensive, or the village has a low crime-rate, Mr. T would suffice.
