Key legal question
Whether the cantonal court violated the presumption of innocence by relying on the police speed measurement.
Extracted holding
No. The court did not shift the burden of proof; the complaint concerned evidentiary assessment, which is reviewed only for arbitrariness.
Extracted reasoning
The cantonal court found the speed measurement reliable based on the officers' statements, video footage, calibration data, and unchanged distance between the vehicles at the start and end of the measurement. The appellant offered only appellatory criticism.
