Defendant’s remaining complaints of inadequate representation refer either to trial tactics within the discretion and judgment of counsel, or to asserted failures to object to introduction of evidence which we have herein found to be admissible. The deputy public defender assigned to this case was an experienced trial attorney, and conducted an active and searching defense. The record bears out the appropriateness of the trial court’s remark to defendant that “You have able and qualified counsel and he will conduct a very good trial in your behalf.” (Cf. People v. Hughes (1961) 57 Cal.2d 89, 99-100 [17 Cal.Rptr. 617, 367 P.2d 33].)
There is no merit in defendant’s contention that the death penalty constitutes cruel and unusual punishment either in the abstract (People v. Bashor (1957) 48 Cal.2d 763, 765 [312 P.2d 255]) or as applied to the facts of this case (see People v. Reeves (1966) 64 Cal.2d 766, 777 [51 Cal.Rptr. 691, 415 P.2d 35]).
Finally, at oral argument defendant contended that the witness, Mrs. Autry Davis, was unsworn because she nodded rather than giving an audible response to the oath administered by the court clerk. Code of Civil Procedure section 2094 provides simply that a witness is sworn by “expressing his assent” when the oath is read to him. While it is doubtless better practice for the witness to voice his reply, in certain circumstances a deliberate nod may be equally expressive of assent. Here the record indicates that Mrs. Davis had some difficulty with her speech, and she responded in this same manner to a number of the questions thereafter put to her by counsel. In any event, if defendant was unsatisfied with the adequacy of the oath-taking, he should have called the matter to the attention of the court. Any shortcomings in the procedure were waived both by failure to object and by taking the witness on cross-examination. (Estate of Wilson (1953) 116 Cal.App.2d 523, 526 [253 P.2d 1011] ; Tennant v. Civil Service Com. (1946) 77 Cal. App.2d 489, 498 [175 P.2d 568]; People v. Duffy (1930) 110 Cal.App. 631, 635-636 [294 P. 496].)
The judgment is affirmed.
