This is a Plod (implied) code message: We need more money
How come Plod, and other 'services' that have a high, often inflated, opinion of themselves want to exclude themselves from the national budget trimming exercise that is currently under way in the UK.
For far too long the outstretched hand of the Plod, often in the disguise of ACPO, has been filed with gold from the immediate pas Labour governments. Under Plunkett, Plod could ask for nothing that wouldn't be answered with yet more funding.
ACPO is also deserving of inquiry, it seems to act like a private fund allocation service with, naturally, the funds coming from the public purse.
The Plod 'thought process' is actually more of a creative process based on the premise of how they can scare the public into pressuring the powers that be in to releasing yet more funds for some adventure in 'empire building'.
