Data Leakage Overlooked
When filling stations started using ANPR to identify bilkers and thereby prevent fuel theft, the Plod wet themselves in their eagerness to catch hold of all that lovely surveillance data. What makes you think that supermarkets and other "ANPR controlled" car parking schemes are not also sending copies of their records to the Police National Computer. In fact I seem to remember someone on this very site moaning about the strictness of formatting demanded by Plod for the ANPR data that they were required to send in daily.
I suggest that many of the ANPR parking companies were set up specifically to gather ANPR data for police use. Can anyone disprove my suggestion?
