Girvies L. Davis was convicted of murder and sentenced to death in the circuit court of St. Clair County, Illinois. After unsuccessfully appealing his conviction and sentence in the Illinois courts, Davis filed this petition for writ of habeas corpus pursuant to 28 U.S.C. § 2254. The district court denied Davis’ petition and he appeals.
I.
On Friday, December 22, 1978, Charles Biebel was shot to death in his mobile home in St. Clair County, Illinois. Biebel, an 89 year-old man who was confined to a wheelchair, was shot twice while inside his trailer. Davis and Richard Holman were indicted and tried for the murder. The evidence at trial established that Davis and Holman burglarized Biebel’s home in addition to killing him. Davis was convicted by a jury of one count of murder in violation of section 9-l(a)(l) of the Illinois Criminal Code of 1961. Ill.Rev.Stat. ch. 38, para. 9-l(a)(l) (1977) (now codified as 720 ILCS § 5/9-l(a)(l)). As required by Illinois law, the court conducted a sentencing hearing to determine whether Davis was eligible for the death penalty. At the sentencing hearing, the jury heard evidence that Davis had been convicted for the murders of two other people in addition to Biebel, and the attempted murder of a third. These prior murder convictions, along with the Bie-bel conviction, made Davis eligible for the death penalty under Illinois law. The jury determined that the necessary aggravating factors existed, and that no mitigating factors were sufficient to preclude the imposition of the death penalty. The jury returned a unanimous verdict that directed the court to sentence Davis to death. The court sentenced Davis to death and the Illinois Supreme Court affirmed his conviction and sentence.
People v. Davis,
II.
On appeal, Davis alleges the following: (1) his sentencing hearing was fundamentally unfair; (2) the Illinois death penalty statute is unconstitutional on its face; and (3) the Illinois death penalty statute is unconstitutionally applied as a general matter and was unconstitutionally applied in this case.
A. Davis’ Sentencing Hearing
Davis contends that his sentencing hearing violated constitutional standards in three ways. First, Davis claims that the use of a taped custodial interview of him by the prosecutor coupled with a remark by the prosecutor that the jury was only to “recommend” the death penalty unconstitutionally injected passion and emotion into the sentencing, violated his right to counsel, violated the Sixth Amendment’s Confrontation Clause, and caused the jury to abdicate its responsibility in considering the death sentence. Second, Davis alleges that he was denied his right to the assistance of counsel at his sentencing hearing. Finally, Davis claims that the prosecutor at his trial systematically and purposefully excluded black members of the ve-nire in violation of the Fourteenth Amendment Equal Protection Clause.
We begin with the videotape. At his sentencing hearing, the trial court allowed the State to play for the jury a videotape of a custodial interview of Davis. Davis said several things to the prosecutor at that interview, including: that he knew of his right to an attorney and did not want his attorney present; that he wanted to be executed quickly for his crimes because he was “tired of living”; that he was a murderer; that Ricky Holman gave him a gun; and that he committed a series of burglaries.
Davis argues that the videotape, together with the prosecutor’s remarks that the jury was only to “recommend” the death penalty, eroded the moral responsibility that the jury felt for Davis’ sentence. Davis’ suggestion that the videotape made the jury more likely to vote for the death penalty is pure speculation. In fact, Davis’ trial counsel, Patrick Young, referred to Davis’ stated desire to die as a
mitigating
circumstance because only someone who was “extremely emotionally disturbed” and not in his “right mind” would make statements like those Davis made during the taped interview. Tr. of Oct. 28, 1980 at 160. And the prosecutor’s comment was an apparent off-hand statement made during the course of the closing argument to the jury. To determine that this lone assertion required reversal, we would have to find that the statement was so inflammatory. and prejudicial as to deprive Davis of a fair trial.
Jentges v. Milwaukee County Circuit Court,
Davis also challenges the use of the videotape because, he says, the interview was conducted in violation of his right to have counsel present. The record reveals that Davis was made aware of his right to counsel
*1138
and waived that right. As required by
Miranda v. Arizona,
MR. KUEHN: Okay. Now, listen to me. I want you to understand your constitutional rights. You understand?
MR. DAVIS: Yes, sir.
MR. KUEHN: Do you have a lawyer? MR. DAVIS: Yes, sir.
* * * * *
MR. KUEHN: You don’t mind talking to me without having him here?
MR. DAVIS: No, I don’t mind talking to you without having him here.
* * * * *
MR. KUEHN: Now, do you understand that you have a right and you can remain silent?
MR. DAVIS: Right.
MR. KUEHN: You can have a lawyer, you’ve got a lawyer. Maybe if you haven’t paid him, you can have one appointed. Do you understand that?
MR. DAVIS: Yes, sir.
Tr. of Oct. 28, 1980 at 113-14.
This exchange demonstrates that Davis waived his right to counsel. A waiver of the right to have an attorney present at a custodial interview, like the one at issue in this case, must be knowingly and voluntarily made.
United States v. Morrison,
Davis says that he lacked the requisite mental capacity to waive his right to counsel. Since Davis was competent to stand trial, (and does not claim otherwise) he was competent enough — and had the capacity — to waive his right to counsel.
Godinez v. Moran,
— U.S. -, -, -,
Next, Davis argues that Kuehn violated his Fifth Amendment right to remain silent. Toward the end of the interview', Davis told Kuehn that “I don’t want to talk no more” and then, as the interview continued, said, “I don’t want to talk about it any more.” Tr. of Oct. 28, 1980 at 128, 131. The interview continued despite Davis’ expressed desire not to talk. By continuing the interview, Davis contends, Kuehn deprived him of his right to remain silent.
A suspect who is subject to a custodial interview enjoys the right to terminate questioning at any time.
Miranda,
Davis also complains that the videotaped material presented to the jury contained hearsay statements that violated the Sixth Amendment’s Confrontation Clause. That provision guarantees that “[i]n all criminal prosecutions, the accused shall enjoy the right ... to be confronted with the witnesses against him.” U.S. Const. amend. VI. But the Confrontation Clause does not apply at sentencing.
United States v. Hammer,
Davis argues next that his trial attorney, Patrick Young, performed so ineffectively that he was deprived of his right “to have the Assistance of Counsel for his defence.” U.S. Const. amend. VI. To succeed on an ineffective assistance of counsel claim, a convicted defendant must show (1) that the defendant’s trial counsel performed deficiently and (2) that the deficient performance prejudiced the defense so as to deprive the defendant of a fair trial.
Strickland v. Washington,
Davis claims that Young was ineffective because he did not present evidence of Davis’ alleged mental illness, retardation', and troubled family background. For this omission, however, Davis has one person to blame — himself. Davis prevented Young from presenting this evidence to the jury during the mitigation phase of the sentencing hearing. Young informed the court outside the presence of the jury that discussions he had with the St. Clair County (Illinois) Mental Health Department led him to believe that Davis had suffered for years from a mental condition and that Davis had received mental treatment for a number of years, going back to early childhood. Young also told the court that those he talked with at the St. Clair County Mental Health Department would testify that Davis received a severe blow to his head when he was a child, that the blow to his head damaged his brain, and that Davis’ E.E.G. readings were very abnormal. Young offered to put on witnesses and enter records into evidence that would confirm what he said about Davis’ mental condition. Young said this would show that “the murder was committed while the defendant was under the influence of extreme mental or emotional disturbance, although not such as to constitute a defense to the prosecution.” Tr. of Oct. 28, 1980 at 18. Young explained that Davis did not want any of that evidence to go before the jury. The court asked Davis if Young was right, that is, if Davis did not want his mental health history presented to the jury. Davis responded with a terse “[t]hat’s correct.” As a result of this, the jury never heard this proposed mitigating evidence. Id. at 19.
Davis was fully informed of the option before him — whether to introduce evidence of his background and mental health history — and informed his attorney and the court that he did not want this evidence to go 'to the jury. He will not be heard to complain that the trial court’s decision to grant his request deprived him of his right to the
*1140
assistance of counsel.
See United States v. Weaver,
Davis relies on our decision in
Brewer v. Aiken,
Davis, a black man, next contends that at his trial the prosecutor systematically and purposefully excluded black members of the venire. This, he says, violated the constitutional guarantee that no state shall “deny to any person within its jurisdiction the equal protection of the laws.” U.S. Const. amend. XIV, § 1. Davis asks us to apply the rule of
Batson v. Kentucky,
Davis urges us to apply
Batson
retroactively. In
Williams,
we considered and rejected the retroactive application of
Bat-son. Id.
at 946.
Batson
would, however, apply if Davis’ conviction was not yet final when
Batson
was decided on April 30, 1986.
Richardson v. Gramley,
As we have explained, Swain requires Davis to show that the prosecutor systematically used peremptory challenges against blacks over a period of time. Davis *1141 has not satisfied this burden of proof. Although Davis alleges that in his case the prosecutor purposefully excluded black veni-re-persons, he fails to show a history of purposeful discrimination. We cannot find from this record that the prosecutor systematically and purposefully excluded black members of the jury in violation of the Fourteenth Amendment.
Given all this, we conclude that there was nothing about the videotaped custodial interview, the prosecutor’s remark to the jury, the prosecutor’s use of peremptory challenges during jury selection, or anything else about Davis’ sentencing hearing that violated the Constitution.
B. Facial Validity of the Illinois Death Penalty Statute
Davis claims that the Illinois death penalty statute is facially unconstitutional because of defects in the statute and, in particular, the statute’s accompanying jury instructions.
1
He charges that the jury instructions do not inform the jury that they may consider nonstatutory mitigating factors and do not instruct jurors on the standard of proof on aggravation and mitigation. Davis also contends that the jury instructions are defective because the instructions cause jurors to believe that capital defendants, like Davis, bear the burden of persuasion on the issue of life or death. All of this, Davis says, violates the Eighth Amendment requirement that “cruel and unusual punishments [shall not be] inflicted.” U.S. Const. amend. VIII. We have described the intricacies of the Illinois death penalty statute before and need not do so here to address Davis’ complaint.
See, e.g., Gacy v. Wellborn,
*1142 Davis first contends that the jurors in his case were not instructed that they could consider nonstatutory mitigating factors. The record reveals otherwise. The trial judge at Davis’ sentencing hearing instructed the jury that mitigating factors may include the five explicitly set out in the statute, but also added a sixth: “Any other facts or circumstances that provide reasons for imposing less than the death penalty.” Tr. of Oct. 28, 1980 at 185. As this instruction indicates, the jury could consider literally anything that in its judgment provided a reason for imposing a sentence other than death.
We considered a similar challenge to similar jury instructions in
Silagy v. Peters,
Davis makes other challenges to the instructions. He contends that the instructions did not instruct jurors on the standard of proof on aggravation and mitigation and that jurors incorrectly understood that he bore the burden of persuasion on the issue of life or death. The portion of the instructions challenged by Davis reads:
A person found guilty of murder may be sentenced to death only if the jury unanimously recommends that the death sentence be imposed.
If, at the conclusion of your deliberations in accordance with the court’s instructions, you unanimously recommend that the death sentence be imposed, then the defendant will be sentenced to death by the court.
On the other hand, if, at the conclusion of -your deliberations, you do not unanimously recommend that the death sentence be imposed, then the defendant will be sentenced to imprisonment for a number of years, not less than 20, to be determined by this court.
Tr. of Oct. 28, 1980 at 180. The court also instructed the jury that:
If, after your deliberations, in this second stage of the sentencing hearing, you unanimously determine that there are no mitigating factors sufficient to preclude the imposition of the death sentence on the defendant, you should sign the verdict form which so indicates. In such a situation, you will be returning one verdict form indicating your verdict on the absence of any sufficiently mitigating factors. If you sign this form, the Court must sentence the defendant to death.
If, after your deliberations, in this second stage of the sentencing hearing, you are not unanimous in concluding that there is no mitigating factors sufficient to preclude the imposition of the death sentence, you must sign the “No Unanimous Verdict” Form. In this situation you will sign one verdict form indicating that you did not unanimously agree on the absence of any sufficiently mitigating factors sufficient to preclude the death penalty. If you sign this form, the Court will sentence the defendant to imprisonment.
Id. at 185-86. In addition to these boilerplate instructions (which track the Illinois death penalty statute), the court explained to the jury that Davis would be sentenced to death only if the jury’s verdict was unanimous and that if the jury was not unanimous he would be sentenced to imprisonment. With all this, and additional clarifying instructions, the jury returned a unanimous verdict directing the court to sentence Davis to death. After the court read the verdict, it asked each member of the jury if each person voted to sentence Davis to death. All twelve jurors answered individually that they voted for the death penalty.
*1143
Davis points to a study conducted by the late Professor Hans Zeisel that purports to demonstrate that the Illinois Pattern Instructions in death penalty cases leave jurors hopelessly confused as to the standard of proof, the burden of persuasion, and a whole host of other factors. We considered Professor Zeisel’s study in both
Gacy
and
Free v. Peters,
As to the burden of persuasion issue raised by Davis, we considered and rejected a similar claim in
Silagy.
We noted that the imposition of the burden of persuasion on a defendant is constitutional because at this point in the hearing, the defendant stands guilty of murder and the prosecution has proven that the requisite statutory aggravating factor exists, thereby making the defendant eligible for the death penalty.
Silagy,
The instructions given to the jury at Davis’ sentencing hearing did not violate the Consti-. tution. The Illinois death penalty statute is not unconstitutional on its face.
C. As Applied Challenge to the Illinois Death Penalty
Davis contends that the Illinois death penalty statute was and is applied in an unconstitutional manner. He charges that in Illinois the death penalty is meted out in an arbitrary and capricious manner so as to discriminate on the grounds of race. Davis also alleges that prosecutors did not request the death penalty for other criminal defendants whose crimes, like his, made them statutorily eligible for the death penalty. Davis points to a study by Samuel Gross and Robert Mauro as support for his claim that in Illinois a person accused of homicide against a white victim is approximately six times more likely to receive the death penalty than a person accused of the same type of homicide against a black victim. The Gross and Mauro study also alleges that a black person who kills a white person is 3.75 times more likely to receive the death penalty than is a white person who kills a white person. Davis argues that the Gross and Mauro study along with the prosecutor’s decision to exclude black members of the venire from the jury demonstrates that the decisionmaking process in his case was infected with racial bias.
We start with the Gross and Mauro study and, for purposes of this case, assume as true the statistical conclusions that Davis describes. Our analysis begins and ends with
McCleskey v. Kemp,
The Court held that the study was not enough to support an inference that any of the decisionmakers in the defendant’s case acted with discriminatory purpose.
Id.
at 297,
McCleskey disposes of Davis’ claim with respect to the Gross and Mauro study. As described by Davis, the Gross and Mauro study purports to show the same things as the study in McCleskey: black defendants are more likely to get the death penalty than white defendants, blacks who murder whites are more likely to receive the death penalty than whites who murder blacks, defendants who murder whites are more likely to receive a death sentence than defendants who murder blacks, and so on. Like the Court in McCleskey, we do not accept Davis’ proposition that his sentence was imposed along racial lines.
Davis was convicted of murdering Biebel. The jury heard additional evidence of Davis’ many other crimes, including two other murder convictions. The jury also heard the testimony of a survivor of one of Davis’ attacks. Davis attempted to kill that person, but failed.
We decline to hold, as Davis urges, that an all-white jury was incapable of rendering a fair decision in accord with Illinois law. As to the apparent discrepancies along racial lines that the Gross and Mauro study announced, we note that such social science studies can cut a variety of ways. For example, the Department of Justice studied murder in large urban counties in 1988. That study concluded that whites and blacks were equally likely to receive the death penalty and that there were no statistically measurable differences in sentencing outcomes between white and black murder defendants. See Bureau of Just. Stats., U.S. Dep’t of Just., Special Report, Murder in Large Urban Counties, 1988 (1993). We need not decide the relative merits of the Gross and Mauro study or the Department of Justice study. We note only that nothing in them, one way or the other, establishes any constitutional violation and certainly does not provide the exceptionally clear proof of discrimination required by McCleskey. That is all we need decide.
Finally, we consider Davis’ assertion that prosecutors in other murder cases did not seek the death penalty and that doing so in his case (and not others) is arbitrary and capricious. Again,
McCleskey
is dispositive. The Court considered the same argument there and concluded that the defendant could not prove a constitutional violation by demonstrating that other defendants who might have been similarly situated did not receive the death penalty.
McCleskey,
One simple fact exists in this case: Davis was convicted of crimes for which the Constitution and Illinois law permit the imposition of the death penalty. The jury heard the evidence, including aggravating and mitigating evidence, and concluded that Davis’ actions warranted the death penalty. That decision was within their discretion, was neither arbitrary nor capricious, and did not violate the Constitution.
III.
The State of Illinois complied with the Constitution when it sentenced Girvies Davis to death. The district court’s decision to deny Davis’ petition for writ of habeas corpus is therefore
AFFIRMED.
Notes
.The Illinois death penalty statute under which Davis was convicted provides in relevant part:
(a) A person who kills an individual without lawful justification commits murder if, in performing the acts which cause the death:
(1) He either intends to kill or do great bodily harm to that individual or another, or knows that such acts will cause death to that individual or another; or
(2) He knows that such acts create a strong probability of death or great bodily harm to that individual or another; or
(3) He is attempting or committing a forcible felony other than voluntary manslaughter. (b) Aggravating Factors. A defendant who at the time of the commission of the offense has attained the age of 18 or more and who has been found guilty of murder may be sentenced to death if:
6s sf! 5k 6* Sf! 6¡
3. the defendant has been convicted of murdering two or more individuals under subsection (a) of this Section....
6s 6s 6s 6s 6s 6s
(c) Consideration of factors in Aggravation and Mitigation. The. court shall consider, or shall instruct the jury to consider any aggravating and any mitigating factors which are relevant to the imposition of the death penalty. Aggravating factors may include but need not be limited to those factors set forth in subsection (b). Mitigating factors may include but need not be limited to the following:
1. the defendant has no significant histoiy of prior criminal activity;
2. the murder was committed while the defendant was under the influence of extreme mental or emotional disturbance, although not such as to constitute a defense to prosecution;
3. the murdered individual was a participant in the defendant's homicidal conduct or consented to the homicidal act;
4. the defendant acted under the compulsion of threat or menace of the imminent' infliction of death or great bodily harm;
5. the defendant was not personally present during commission of the act or acts causing death.
(d)Separate sentencing hearing. Where requested by the State, the court shall conduct a separate sentencing proceeding to determine the existence of factors set forth in Subsection (b) and to consider any aggravating or mitigating factors as indicated in Subsection (c). The proceeding shall be conducted:
1. before the jury that determined the defendant's guilt[.]
(g) Procedure — July.... If there is a unanimous finding by the jury that one or more of the factors set forth in Subsection (b) exist, the jury shall consider aggravating and mitigating fáctors as instructed by the court and shall determine whether the sentence of death shall be imposed. If the jury determines unanimously that there are no mitigating factors sufficient to preclude the imposition of the death sentence, the court shall sentence the defendant to death.
Unless the jury unanimously finds that there are no mitigating factors sufficient to preclude the imposition of the death sentence the court shall sentence the defendant to a term of imprisonment under Chapter V of the Unified Code of Corrections.
