"Vehicles are likely to get damaged in many circumstances, including pursuits, general travelling and offenders trying to evade police. Vehicles are also damaged during disorder events where a crowd may turn on police."
Mr Brown said, despite police efforts, vehicles did get damaged due to the "nature of the job".
