I agree with Droopy and rotordk. As a Police pilot your patch is overland and what you see out of the window is what you get throughout your patch so you do your own mental TAF.
In the N Sea there is a variation in the weather over our very large patch and we tend to operate to min fuels to give the customer max payload. It is not a comforting thought to approach your destination airfield with VFR fuel (30mins holding no div) to find it's ATIS is giving reports that are close to or below limits (200ft 500m) when the TAF has forecast above 600ft and 4000m!
You may be surprised that one of our major airfields (Sumburgh) doesn't even have a forecaster on duty when we are planning our morning sorties despite the vast amount of tax the oil companies pay. This is why we MOR inaccurate TAFs to try and get something done about the lack of forecasters.
Being based at Liverpool you may have heard or seen the Dauphines of Bond leaving and arriving IFR when you where stuck on the ground because of weather. This is why we require accurate TAFs. After all we can't land in a field if the weather is worse than forecast!!
