Plot holes

Instead of simply losing his job, Kessler would have been immediately arrested and charged for planting evidence.

Plot holes

At the end of the film, Warren is distracted by the transmissions on the police radio while searching for Laurie. The radio was given to Laurie by McAnn long before Warren is arrested for murder. Yet she still has it after his trial, when there is no reason for her to keep it following the arrest as it a tool to contact McAnn should Warren make another obscene call to her. Furthermore, no charging device is given with the radio, so the battery would have long been flat. It is highly likely that a property officer at the police station would also have noticed its absence for such an extended period and would have questioned McAnn as to its whereabouts for inventory purposes.
