Can a defendant be restrained in the courtroom while in the jury's presence?

"[A] defendant cannot be subjected to physical restraints of any kind in the courtroom while in the jury's presence, unless there is a showing of a manifest need for such restraints. [Citation.]" (People v. Duron (1976) 16 Cal.3d 282, 290-291, 127 Cal.Rptr. 618, 545 P.2d 1322, fn. omitted.) In the present case, the Attorney General concedes that the trial court abused its discretion in ordering defendant restrained, because no such showing of a manifest need for the leg brace was made, but argues that the error was harmless. We agree.
