What were the facts given to the Air Support Unit at the time of the deployment?
For instance, if it was simply a Making Off Without Payment - this is probably not worth a deployment, but if the aircraft was in the area, it was a distinctive vehicle, if it was involved in other crime, if it was being pursued by police, if there had been an armed robbery, if Police Officers had been threatened with weapons, a child had been abducted, it was being driven by Elvis.......
By the same token, I have experience of 'the facts' being sexed up in order to force a deployment of an aircraft for a crock of sh1t !!
