Questão jurídica principal
Whether the cantonal chamber arbitrarily upheld the dismissal of the criminal complaint.
Decisão extraída
The evidence supported the officers' version, and the cantonal assessment was not manifestly untenable or arbitrary.
Fundamentação extraída
The police account was corroborated by vehicle photographs and was plausible; the contrary version was not supported. Further investigative steps were at most conceivable, not required, so the refusal to continue the inquiry was not arbitrary.
