According to reports that investigated police, they're letting much worse crimes slip than this one (which I still think should've bene a slap on the wrist instead of charges).
Area I'm in, it's a regular drug dealers nest, yet because at least one of them also snitches on the others, she gets to stay free to carry on her business. If they can't be arsed to nick one dealer, then arresting someone that found a £20 note seems to me way over board.
Well lets see... dim woman caught on camera with witnesses and an annoyed victim for a quick and easy result or....
Spending days trying to get enough evidence to stick on a suspected dealer with a huge maybe over the result.
Funny how they don't find time to harass your dealer.
