Because Preventive Law is also, or is essentially, a cultural and citizenship issue (not least because, in theory, anyone agrees with the principles of Preventive Law, but, in practice, few dispense with the winner-defeated logic of the system “ vertical ”), any good idea to involve citizens in the application of justice, using the horizontal system of Preventive Law, is a good idea.

We briefly address here the successful American experience of the Youth Courts of Peers, which, while not being a scientific application of Preventive Law, demonstrates that, in practice, its principles, even if not studied, are easily intuitive by all – which it shows, first of all, that Preventive Law is more natural to man than Reactive Law.
