In the UK you won't see police standing outside just about every bank, supermarket and street corner in the centre of towns and cities. And if you do they certainly won't be smoking or playing with their mobile phones.You have described police all over the world UK. This what is done while out in the field.
Go past a construction site needing a policeman at either end to regulate the flow of two way traffic
In short, police have little to no oversight in the field. Without supervision and accountability this is what you / we get from our public servants.
Plus, in the UK it's usually the job of traffic wardens to faff about directing traffic. The police only get involved when someone naughty is breaking the law....like driving after over imbibing in the 'uisge beatha'.
