Is it relevant and proper for a police officer to testify that he witnessed a witness identify a defendant in a lineup?

Testimony of identifying witnesses descriptive of their identification of a defendant from pictures and at a lineup was relevant and proper. In People v. Slobodion, 31 Cal.2d 555, 559-560, 191 P.2d 1, 4, the court concluded, after a review of the cases: 'the evidence by the prosecutrix that she identified defendant in a lineup after the offense was admissible to corroborate her story and to rebut the suggestion that her identification at the trial was the result of recent contrivance. The same considerations apply to the testimony of the police officer that he saw the witness identify defendant.' See also People v. Hood, 140 Cal.App.2d 585, 588, 295
