Unit IV - The law.

The most famous police Station in Britain is New Scotland Yard in London. They've all got a blue light outside to show they are police stations.
For most people the police are the face of the law.
When they arrest a criminal, they see how has got in the pockets.
Suspects can be kept in the cells at the police station for several hours.
Next day they went to court, and there three magistrates listen to evidence from the police and witnesses. Then, they decide if the person is guilty or not guilty.

The police are the most obvious part of the law in Britain. Their job is to make sure that people don't break the law and to catch them when they do.
Forensic scientists provide the evidence that helps the courts decide whether is guilty or not guilty of a crime.
