Defendant-appellant Filemon Amaro was convicted in the district court of voluntary manslaughter of a fellow inmate, an offense he committed while incarcerated at the Marion, Illinois federal penitentiary in violation of 18 U.S.C. § 1112. After being sentenced to a ten-year period of confinement, Amaro appeals. Hе argues the district court committed reversible error in requiring his inmate witnesses to wear restraints while testifying, in admitting a statement he made during custodial interrogation which supposedly violated his Miranda rights, and in improperly excluding evidence of the history of violence at the Marion penitentiary in support of his theory of self-defense. We affirm.
I.
Amaro alleges the district court erred in requiring his inmate witnesses to testify in front of the jury while wearing physical restraints. He argues that requiring his witnesses to wear handcuffs and leg irons 1 without holding a hearing on the necessity of such measures detracted from his witnesses’ credibility and harmed his defense.
While as a general rule a defendant has a right to have his witnesses appear before a jury free from shackles or other physical restraints, this right is not absolute.
Harrell v. Israel,
One such justification for the use of restraints is the witnesses’ history of violence in the face of maximum security precautions, beсause there is grave danger of their attacking people in the courtroom or trying to escape.
United States v. Fountain,
Where the trial judge, however, makes every effоrt to prevent the jury from becoming aware of the restraints, and the record shows he was successful in so doing, this court has held that the failure to demonstrate the requisitе need for restraints was not reversible error. Id. at 636-37. Here, the district court took every precaution to prevent the jury from viewing the restraints by placing the inmate witnesses on the stand before the jury entered the courtroom. In addition, the judge did not require the people in the courtroom to rise when he entered, so that the restraints would not be noticed. Insofar as the record shows the court was successful in preventing the jury from becoming aware of the restraints.
Furthermore, because Amaro was charged with voluntary manslaughter of a fellow inmate, the jury was required to know that both Amaro and his witnesses were inmates of a maximum security prison. “Given the nature of such institutions,
*286
it is not unreasonable to assume that the jury would naturally expect that when inmates appear in court, either as parties or witnesses, adequate security measures would be taken.”
Id.
at 638. Any prejudice caused by the restraints was mitigated by the jury’s awareness that the witnesses in the case were prison inmates and guards; henсe, the “shackles could not have come as much of a surprise,”
Fountain,
Finally, we note that Amaro raised no objection to the district court’s shackling order when it was issued. We find the fact that Amaro did not object supportive of our conclusion that the trial judge did not abuse his discretion; had some objection been made, fuller consideration сould have been given the issue of insuring courtroom security and lesser alternatives considered.

II.
Amaro also contends that his custodial statement was inadmissible because it was made in violation of his Miranda rights. The record reveals that Amaro was interviewed by two FBI agents and two prison staff officials on the morning of the incident in question. Amaro was advised of his rights and acknowledged that he understood them. He then stated that he did not want to talk to the FBI agents, but he indicated he would talk to the prison officials. The two FBI agents and a prison official left. Amaro then gave a statement to the remaining prison official indicating that the altercation was just between the victim and him, and no one else was involved.
While the Supreme Court has stated that a defendant’s right to cut off questioning must be scrupulously honored,
Miranda v. Arizona,
III.
Amaro claims that the district court improperly excluded evidence of the climate of constant fear at the Marion federal pеnitentiary. Specifically, he argues that the district court should have admitted a report and recommendation of a district court magistrate in an unrelated civil case which allegedly established that there was a history of assaults at the Marion penitentiary. Amaro avers that this evidence was relevant to his theory of self-dеfense because it tended to prove that his use of force against the victim was reasonable. See, e.g., Seventh Cir. Fed. Crim. Jury Instruction 4.01 (stating that a person is justified in using force intendеd or likely to cause death only if he reasonably believes such force is necessary to prevent death or great bodily harm to himself).
Evidence is relevant if it has “any tendency to make the existence of any fact that is of consequence to the determination of the action more probable or less prоbable than it would be without the evidence.” Fed.R.Evid. 401. This court has recognized that the federal rules of evidence and practice favor evidence being admitted rather
*287
than excluded if it has any probative value at all.
United States v. Anderson,
Here, there was no abuse of discretion. By Amaro’s own explanation, thе report would have shown a history of assaults in the institution during a period before 1980. The altercation in this case which resulted in the death of an inmate occurred in 1984, а date not within the time frame of the magistrate’s report. Because the report would not have been relevant to the state of the prison in 1984, when the altercation took place, and Amaro did put in evidence of the assaultive nature of the inmates at Marion, the district court did not abuse its discretion in not admitting it into evidеnce. Therefore, the judgment of the district court is
Affirmed.
Notes
. Amaro claims his witnesses were required to wear waist chains as well as leg irons and handcuffs. The record reveals, however, that the court specifically ordered that Amaro would wear handcuffs and leg irons, and that it would follow the same procedure for the inmate witnesses.
