Rather than give the entire feed to the police, surely it is possible to
obtain a compromise whereby certain hashes can be added to a "watch list".
Upon matching, the entire car index plate, location etc is revealed to the
police.

Oversight will then consist of accurate reports by the council/HA etc of the
number of plates concurrently on the watch list each reporting period.

This at least prevents some enterprising police forces storing the raw feed
indefinitely.
