Jerry Dean Mills stands convicted of escape from the Ada County jail. In this appeal, he asserts that the district court erred by (1) restricting his voir dire of the jury; (2) interrupting his opening statement; (3) requiring his inmate witnesses to wear leg irons while testifying; and (4) altering his proposed jury instruction on the defense of necessity. Mills also asserts (5) that there was insufficient evidence to support the jury verdict. We affirm the judgment of conviction.
The issues are framed by these facts. Mills had been incarcerated at the Ada County jail for several months. Throughout his confinement he had complained repeatedly to the jail staff about severe and *536 persistent headaches. The staff responded by sending him to a dentist and by arranging frequent appointments with the physician’s assistants at the jail, who provided him with Tylenol. When this treatment proved unsatisfactory, Mills was seen by two doctors and a psychiatrist. They diagnosed Mills as suffering severe tension headaches which were not life-threatening. Mills told the jail staff that he was not satisfied with this diagnosis, and that he needed stronger pain medication. Just pri- or to a scheduled transfer to the Idaho State Correctional Institution (ISCI), Mills escaped. Nine days later he was arrested in Montana for a different crime. Mills was extradited to Idaho where he was charged with escape. He asserted a defense of necessity, but a jury convicted him. He now appeals.
I
Mills first contends that the trial court improperly limited the scope of his voir dire, restricting any meaningful inquiries into the jurors’ attitudes on the trustworthiness of penitentiary inmates or on prison medical care. We disagree.
The scope of voir dire is a matter resting in the discretion of the trial court.
State v. Pontier,
II
Mills next contends that the trial court improperly prevented him from setting forth his theory of the case during his opening statement. The Idaho Supreme Court has held that the trial court has discretion to limit the scope of the opening statement.
State v. Griffith,
Here, during opening argument, counsel for Mills began to explain a proposed jury instruction when he was interrupted once by the judge and told not to argue the law at that point. There were no other comments by the court during defense counsel’s opening statement. We find no abuse of discretion.
Ill
We next consider Mill’s argument that he was unfairly prejudiced when the trial court required his witnesses to wear leg irons while testifying. The decision to require restraints is another matter within the trial court’s discretion.
State v. Moen,
Our Supreme Court has set forth procedures for the trial judge to use in deciding whether a defendant must be physically restrained during trial.
See Moen,
In the case before us, the judge followed the procedures established in Moen. Mills called three inmate witnesses. All had *537 been convicted of felonies, and one had recently been charged with inciting a riot. In a hearing outside the presence of the jury, the state asked to have them shackled. Mills objected to the shackles but did not suggest any less visible means of restraint. The district court concluded that the state’s requested security measures were reasonable. The court noted that the witnesses’ status as prison inmates would be made known to the jury in any event, as part of their testimony about Mills’ escape. Because Mills did not present the judge with less visible alternatives, we find no abuse of discretion.
IV
We now turn to the court’s instruction on the necessity defense. Mills argued at trial that he escaped to avoid danger to his health. Mills now contends that the jury was misled by the instruction given. When we review a jury instruction, we pay careful attention to the language used and consider how reasonable jurors would interpret it.
State v. Gilman,
The instruction at issue here was the following:
A person who is in a situation where it appears that he is in real danger has the right to act upon appearance, providing his apprehension of danger is such as would appear to a reasonable person under like or similar circumstances, even though such appearance may prove to be wrong.
Mills challenges the phrase “providing his apprehension of danger is such as would appear to a
reasonable
person.” He contends that the instruction served as an invitation for the jury to discount the veracity of Mills and his witnesses. We disagree. The instruction does no more than explain to the jury the well settled principle that the necessity defense (in the escape context) is governed by an objective, not a subjective, standard.
See, e.g., State v. Stuit,
V
Finally, Mills contends there was insufficient evidence to sustain the jury verdict. Appellate review of the sufficiency of the evidence is limited in scope.
State v. Decker,
Here, the fact of escape was undisputed. Mills’ only defense was his claim of necessity. However, there was very little evidence to support this claim. In order to establish the necessity defense, Mills had to show (1) the threat of death or danger of serious imminent harm; (2) the futility of reporting the threat or danger to custodial authorities; (3) avoidance of violence during the escape; and (4) intent to contact another law enforcement agency immediately following the escape.
See, e.g., State v. Urquhart,
The judgment of conviction for escape is affirmed.
