Question juridique clé
Whether Art. 32 StGB and §§ 27-28 of the police duty regulations justify the officer's use of a firearm
Solution extraite
Police firearm use can be justified by official duty under the duty regulations, subject to proportionality and the specific regulatory limits.
Motifs extraits
The court held that the relevant regulations, not only formal statutes, may provide the legal basis. The proportionality principle still applies, and the firearm rules in the duty regulations concretize when official duty can justify the conduct.
