ing that the conversations were not inappropriate, that is, in any way trial related or that they were harmful to appellant. The conversations, as the trial judge stated, in ruling on appellant’s objection, should not have occurred, but they being unrelated- to the trial, no harm occurred.
In reviewing the record, it appears the conversations were so brief, so innocuous and so unrelated as not to constitute misconduct. The essence of juror misconduct, as defined in Penal Code section 96, involves communications relating to the trial. The United States Supreme Court in Remmer v. United States (1954) 347 U.S. 227 [98 L.Ed. 654, 74 S.Ct. 450], ruled that “In a criminal case, any private communication, contact, or tampering, directly or indirectly, with a juror during a trial about the matter pending before the jury is, for obvious reasons, deemed presumptively prejudicial .. .. ” (Id. at p. 229 [98 L.Ed. p. 656].) The trial judge properly inquired into the conversations and made a finding that they in no way related to the trial. His finding was entirely supported by the evidence.
For a second reason, the judgment on this issue was proper. Trial counsel merely objected and made no motion to excuse the juror for cause and substitute an alternate juror, if there was any, or to move for a mistrial. Any such error was waived thereby. (Dimmick v. Alvarez (1961) 196 Cal.App.2d 211 [16 Cal.Rptr. 308].)
3. A. thorough review of the record demonstrates that the issue of amenability to treatment of appellant was not in any way raised at trial by appellant’s counsel in argument or in requests for jury instructions, or at all. Therefore, the question is, should the trial judge have instructed the jury sua sponte that in addition to the finding of “dangerousness, ” they must additionally find appellant was amenable to treatment?
Although the issue of amenability is much discussed in several cases involving the extension commitments of mentally disordered sex offenders (MDSOs) under Welfare and Institutions Code section 6316.2, our research discloses no case involving the extension of the commitment under Penal Code section 1026.5, subdivision (b), of a person previously-found not guilty by reason of insanity.
There are, in fact, two lines of authority in the Courts of Appeal as to whether amenability to treatment is an issue in extending commit-
