The term "Kriminalpolizei" refers to the criminal police in Germany, responsible for investigating serious crimes such as murder, robbery, and fraud. This specialized branch operates under the jurisdiction of state police forces and focuses on gathering evidence, interviewing witnesses, and solving cases. Kriminalpolizei officers often work closely with other law enforcement agencies, including the Bundeskriminalamt (Federal Criminal Police Office), to tackle organized crime and terrorism. They utilize various techniques, including forensic science and surveillance, to ensure public safety and uphold the law.
