Organizational structure and functions of the police
As we know, the police all over the world are united by commongoals. There are ensuring law and order, civil protection and investigation of crimes. But the structure of law enforcement agencies may differ from country to country. If you live in the US and at least once have been in the police station, then you are familiar to work organization “open space” and do not be surprised by appearance of police workplaces in other countries, as they can be equipped in different ways. As for the structure, it can be centralized and decentralized. We will examine with you the structure of the police in the United States.
There are various police services, which generally operate independently of each other; each one is investigating his case. But when it is necessary, they may interact. This structure of law enforcement agencies may be called decentralized. Departments and police agencies are presented in every district, in every city, in every village. If something will happen to you, you can always go to the police.
For example, in Sweden the police are centralized, there created only one agency that is responsible for keeping order and for the investigation of all crimes. If the US police is completely decentralized and in Sweden, on the other hand, is absolutely centralized; then in many other countries varying degrees of police centralization exists. So in Canada, there are Mounted Police, which controls the order in the streets only and other police services take care of all the other responsibilities. The structure can depend on various criteria: share by districts or by geographical location, by the duties, etc.
Legal bases of police work
As we found out, the main objective of the police is to maintain law and order and protect the public. In the case when crime is committed or offense is only planned, the police in different countries might behave differently. For example, in the United States a person may be detained in a case when there are compelling grounds for it. But in some European countries, you can be detained, if only the police will find you guilty. And to prove your truth you'll be while in police custody. In such a way, we understand that each country set its own laws of justice.
