Question

The United Kingdom doesn't have only one police force. Instead, there are 50 different forces around the country! At the head of each force is the Chief Constable (or, in London, the Commissioner). There are different ranks of police officers. Police constables, under the supervision of sergeants and inspectors, do the general police work, such as patrolling the streets, answering calls and so on. The police station is their base. Entry to the police force is open to men and women over the age of 18 who are physically fit and have good eyesight. Every police officer does two years of police college courses and on-the-job training. Police constables wear a uniform and a helmet. They do not carry a gun. Detectives, who investigate crimes, wear plain clothes. по этому тексту​
