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

"Under California law, '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.] Similarly, the federal 'Constitution forbids the use of visible shackles . . . unless that use is "justified by an essential state interest" such as the interest in courtroom security specific to the defendant on trial.' [Citation.] We have held that these principles also apply to the use of an electronic 'stun belt,' even if this device is not visible to the jury. [Citation.]" (People v. Lomax, supra, 49 Cal.4th at p. 559.)
