Abstract
This article draws attention to the violent extremism perpetrated by juveniles in Switzerland; the author warns that the political and media attention paid to cases related to this phenomenon creates the risk that decisions will be unbalanced between the criminal sentence and the trial pedagogy that characterizes common law for juveniles. Furthermore, it warns that the desire to protect society in accordance with the so-called precautionary principle should not take precedence over other considerations relating to the condition of juveniles.
