Community police
There is a new type of police officer on our country roads these days. They’re not real police officers. They are members of the public and they are called ‘community police’. The idea is that they help the police control the speed of motorists through their villages.
These people wear yellow jackets and stand beside the road with a traffic gun pointed at the cars to find out the speed. This is not official. There is no camera and the people have to note down the numbers of the cars that are going too fast. This information is then passed on to the real police who send a warning letter to the owner of the car.
Not everyone is happy with this scheme! ‘It’s not a good system,’ says Mark Good from one of the main motoring organisations. ‘Mistakes often happen. The people take down the wrong numbers! The information is just not reliable. It’s never a good idea to get the public to do the police’s job. I think it’s ridiculous.’
But, as the villagers say, speeding is a huge problem, particularly in the countryside. There aren’t enough traffic police and dangerous motorists need to be stopped. So what do you think? Let us have your views on the website. www.tellus.com
