Its called selective law enforcement. If it wont cost the county any money, and its not violent, they may persue a case.In this county, some folks have been arrested for numerous DUI stops, why aren't they in jail? Costs to house them.One nortern suburb close to where qwe used to live, had a shop lifter, female, ready to deliver, and sick, guess what the local mounties did? They took her to her own town, and turned her loose. It would have cost the city thousands for the medical care.The merchant screamed bloody murder, it didn't help, but suddenly parking laws around the business became more enforced, and customers were ticketed for things that were ignored by another store in the same mall. But steal 10 bucks from a bank!!!
