Key legal question
Whether the cantonal court's assessment of the evidence and finding of guilt was arbitrary
Extracted holding
No. The testimony of the police officer and the photographs did not make the conviction untenable; the mistaken description of the route had no effect on decisive facts.
Extracted reasoning
Federal review in a public-law appeal is limited to arbitrariness. The record did not show manifestly incorrect evidence appraisal, and the defendant failed to rebut the alternative grounds relied on by the cantonal court.
