Questione giuridica chiave
Whether the factual findings on speeding were arbitrary and violated in dubio pro reo
Decisione estratta
No. The canton court could rely on the consistent testimony of the two sworn officers and on their speedometer-based observations, with a safety margin deducted.
Motivazione estratta
The federal court held that such testimony can suffice for proving speeding; the appellant's criticisms were mainly appellatory and did not show manifest insoutenable assessment of evidence.
