Some other differences, explained in short:
- the German prosecutor has formal responsibility for investigation, and the police are considered to be a subordinate helping agency,
- there's a single national criminal code, a single national code of criminal procedure, and unified court system,
- the German police are not allowed to arrest a suspect simply because they have probable cause to believe that the suspect has committed an offence. They are permitted to arrest without a warrant only when the suspect is caught in the act or when there is a risk of flight or a problem in identifying the suspect. (Detention for longer than one day requires a warrant issued by a court.)
