In Mexico, some law enforcement agencies may use unmarked vehicles for investigative or intelligence purposes.
However, when an authority makes an arrest or conducts an intervention, it must comply with the provisions of the Political Constitution of the United Mexican States, which requires that all acts of authority be duly justified and motivated.
Furthermore, the National Code of Criminal Procedure establishes that the police must identify themselves and inform the person of their rights when making an arrest.
It is also important to know that the use of police equipment, lights, and uniforms must be official and registered in accordance with the General Law of the National Public Security System.
This type of information is part of civic education, helping people understand how authorities must act in accordance with the law.
