Kernrechtsfrage
Whether preventive detention under Art. 43 Ziff. 1 Abs. 2 StGB was required instead of a stationär treatment order.
Extrahierter Entscheid
Because the respondent posed a serious danger to life and bodily integrity and the prospects of treatment success were too uncertain in the short to medium term, refusing preventive detention violated federal law.
Extrahierte Begründung
Preventive detention is ultima ratio, but it is justified where a dangerous offender remains possibly dangerous despite treatment and the healing prospects are highly uncertain; the lower court gave excessive weight to treatment optimism and the practical possibility of later substitution.
