In December 2015 the police in Essen questioned a speaker of Arabic who they suspecting of stealing a jacket and some drinks from a supermarket. As they could not understand Arabic, they consulted Google Translate, RP Online reports. As the paper points out, this appears to be an infringement of the right to a fair hearing (Anspruch auf rechtliches Gehör). The police say they used the program to establish the man’s identity. It looks as if there will be no conseqences, since the man was given an interpreter the next day and at following hearings. The public prosecutor’s office in Düsseldorf confirmed what had happened, but did not answer the question as to whether the police often use Google Translate.
