"Steady" means that the facts of the case are fixed by evidence, so that the proved facts are unshakable, especially the main facts proved are in a static state and will not change or be changed. Only the facts of the case can determine the nature and legal attributes of the case. "Identity" refers to the uniqueness of identification evidence that eliminates inferences and possibilities, that is, eliminates all reasonable doubts, and ensures that investigation, prosecution, defense, and trial have consistent understandings and no objections. Continuously strengthen the judicial concept of "doubtless suspicion". When the facts and evidence of the case are "doubtful" and there is a "choice between the two", they will not be recognized based on the principle of favoring the defendant. When the defendant claims that the investigative agency has used torture to extract confessions, the investigative agency must provide evidence in accordance with the principle of reversal of the burden of proof. If the investigative agency cannot prove that it did not use torture to extract a confession, the defender's defense opinions should be adopted. The above knowledge is my answer to relevant legal questions. Anyone who knows the facts of the case has the obligation to testify. Therefore, witnesses in criminal cases can provide evidence, but the evidence provided by the witness must be true and legal, and no perjury can be provided.
