/ˈsoʊʃiːs krɪˈmɪnɪs/ – Phrase
Definition: Người cùng phạm tội.
A more thorough explanation: a Latin term used to describe an accomplice to a crime (=someone who has taken part in a crime, but who was not the main criminal involved)
Example: In the Scots criminal courts, when a socius criminis appears as a witness for the crown, he is told by the judge that his evidence will not militate against his crimes.
