If you read the small print in most councils parking regulations, their vehicles are exempt from being ticketed if they are watering the flowers, emptying car park machines, etc etc. How on earth they can issue a ticket to a marked police vehicle is beyond me, no common sense whatsoever, talk about working in partnership. their managers should sort them, unfortunately they are probably being directed to do it by the manangers, like most other things to do with councils, it's all statistics, just numbers. Councils have been given far too much power by the government, and have continued to abuse most of it, like use of PNC and surveillance etc.
