Major crimes unit of the police

Hello, I am a police worker. I want to answer this question. In most areas of our country, there is no major crime unit, which is purely a TV interpretation. Generally, when a major case occurs, the leaders will be transferred from the police force, and the elite major crime unit, including criminal police, forensic doctors and judicial police, will be seconded. When the case is solved, the major crime unit disappears and all the people will return to their police force! However, generally in each branch, there will be a public security brigade, which has the same function as the major crimes unit you think about! Absolute authoritative answer
