EDITH H. JONES, Circuit Judge:
On initially hearing this case, the majority of a panel of our court concluded that an accumulation of actions prejudicial to petitioner George Guy Derden deprived him of a fundamentally fair trial for burglary in Mississippi state court. Derden v. McNeel, 938 F.2d 605 (5th Cir.1991). After en banc rehearing, we now hold that federal habeas corpus relief may only be granted for cumulative errors in the conduct of a state trial where (1) the individual errors involved matters of constitutional dimension ráther than mere violations of state law; (2) the errors were not procedurally defaulted for habeas purposes; and (3) the errors “so infected the entire trial that the resulting conviction violates due process.” Cupp v. Naughten, 414 U.S. 141, 147, 94 S.Ct. 396, 400-01, 38 L.Ed.2d 368 (1973). This case fails to satisfy those standards.
I. BACKGROUND
A rational jury could have convicted Der-den of participating in the burglary of Wade’s Grocery in Pheba, Mississippi [1455]*1455shortly after midnight on February 10, 1983.1 The burglars unsuccessfully attempted to remove a safe, then fled in mid-crime at the sight of an approaching vehicle. Three of the burglars, each of whom had reached a very favorable deal with the prosecution, testified to Derden’s involvement. The co-conspirators were Willie Sherrod, who worked at Derden’s carpet store in Columbus, Mississippi and had a string of armed robberies in his past, and Jay Posey and Tommy Turner, young men who first met Derden the night of the burglary and barely recognized him later. They all testified that Derden drove them in his van with his girlfriend Pam Smith to Wade's Grocery and was participating in the crime until it aborted. Derden, Turner and Smith escaped in the van, leaving Po-sey and Sherrod to hitchhike through the darkness and rain. At a nearby farmhouse, Posey and Sherrod found a ride back to Turner’s West Point, Mississippi apartment. According to Turner, the group in Derden’s van experienced car trouble and drove along back roads, finally dropping Turner off in West Point before Posey and Sherrod arrived. Derden was stopped in his van and ticketed at 3:45 a.m. for having broken tail lights.
In his defense, Derden tendered an alibi and challenged the credibility of the other burglars. His alibi was supported principally by his own testimony and that of Pam Smith. According to this tale, Derden had lent his van to Sherrod that night while he and Smith went to Houston, Mississippi in Sherrod’s car and measured two houses for carpet until midnight. Neither Smith nor Derden, however, had been able to identify the houses or their occupants. The alibi was subjected to devastating cross-examination.. For instance, Derden. produced receipts and business records of minutiae such as three-year old gasoline purchases, yet he had mysteriously lost the receipt for the carpet he sold in Houston that night. Further, Derden’s counsel agreed with the prosecutor to introduce in evidence Der-den’s statement to the sheriff, made during investigation of the crime. As luck would have it, some hearsay information on that statement directly contradicted Derden’s testimony that he switched vehicles with Sherrod at the Apollo Club the night of the burglary.
Derden sought to undermine the confessed burglars’ testimony by emphasizing the favorable treatment they received from the prosecutors. He also tried to show that their chronologies of events were hopelessly inconsistent, hence untrustworthy. The farmer’s son who agreed to give Sherrod and Posey a ride when they showed up on his father’s doorstep after midnight testified that he dropped them off in West Point by about 2:00 a.m. All three burglars testi--fled that Turner had returned to his West Point apartment before Sherrod and Posey. But according to the sheriff who investigated the crime, the route of Turner’s odyssey in Derden’s van, which included a stop to work on the tail light, could not have landed Turner at home until well after 3:00 a.m.
The jury found Derden’s defense unpersuasive. He was sentenced to seven years in Mississippi state prison. Qn appeal to the Mississippi Supreme Court, Derden raised numerous points of error similar to those he later argued in federal court: prosecutorial misconduct during voir dire, judicial bias, withholding of exculpatory evidence, and lack of fundamental fairness.2 [1456]*1456With one exception, the Mississippi Supreme Court found Derden's arguments so meritless that" they warranted no discussion. See Derden v. State, 522 So.2d 752, 755 (Miss.1988). The state supreme court did rule that the prosecutor violated Mississippi law in the conduct of voir dire on the co-conspirators’ testimony, but it held that this error was later cured by the trial court’s jury instruction.3
Unsuccessful on direct appeal, Derden sought habeas corpus relief. He persuaded the magistrate that “the trial judge’s demeanor coupled with the prosecutor’s over-zealous actions” impugned Derden’s credibility in a case that hinged on credibility choices and produced a pervasively prejudicial trial atmosphere. The district court rejected the magistrate’s conclusion and held that the cumulative effect of the events at trial did not fatally undermine its fundamental fairness or the accuracy of the verdict. The panel majority in this court read the record and held that the challenged events at trial were so unfair to Derden that while not individually meriting the grant of the Great Writ, they cumulatively violated his constitutional right to due process. We reverse course again, and, disagreeing with the panel majority’s application of the cumulative error theory, we affirm the district court’s denial of relief.
II. DISCUSSION
That the constitutionality of a state criminal trial can be compromised by a series of events none of which individually violated a defendant’s constitutional rights seems a difficult theoretical proposition and is one to which the Supreme Court has not directly spoken.4 With one exception, however, our sister circuits have held in dicta that federal habeas relief may issue if a defendant was denied fourteenth amendment due process by the cumulative effect of errors committed in a state trial, which together deny fundamental fairness.5 We join the majority “rule” subject to the following discussion.
Several of the circuit court decisions drew an analogy with cases on direct criminal appeal in which the possibility of cumulative error is often acknowledged but practically never found persuasive.6 Such rote [1457]*1457analogy is misleading. The standard for reversal on direct appeal of a criminal conviction, whatever it may be, should logically be more flexible than that available on collateral review. We are not here considering the basis for cumulative error review on direct appeal of federal convictions. However, because the habeas cases have also rejected cumulative error theories on the facts presented, their definitions of it are perfunctory. As an example, the Sixth Circuit describes cumulative errors as those that do not individually deny due process “but, when considered together, leave ‘no doubt that the jury was too tainted and influenced to be able to give the petitioner a fair trial.’ ” Lundy, 888 F.2d at 481. Our research has revealed only two cases in which federal habeas relief was granted because of an accumulation of trial court errors. In these cases we may glimpse the rationale for the cumulative error theory. This court essentially relied on such a theory when it granted the writ to a defendant whose trial was overshadowed by an ambiguous stipulation that prevented him from arguing an insanity defense while the prosecutor repeatedly asserted, contrary to overwhelming medical evidence, that the defendant could not have been insane when he murdered his wife and slashed his own wrists. Guidroz v. Lynaugh, 852 F.2d 832, 837 (5th Cir.1988). The results of these errors likely led to the rendition of an inaccurate verdict. In Walker v. Engle, 703 F.2d 959 (6th Cir.1983), cert. denied, 464 U.S. 951, 104 S.Ct. 367, 78 L.Ed.2d 327 (1983), the court found that six types of evidence introduced by the prosecution were calculated “to arouse prejudice against the defendant to such an extent that he was denied fundamental fairness.” 703 F.2d at 968. The trial was “inflamed by marginally relevant and irrelevant evidence that was highly prejudicial.” Id. The prejudicial evidence allowed the trial “to focus more on the claimed corruption of the Sheriff’s Department than on the issue of Walker’s guilt or innocence ...” of first degree murder.7 Id. These cases fit the Supreme Court’s description of a denial of due process as “the failure to observe that fundamental fairness essential to the very concept of justice. In order to declare a denial of it we must find that the absence of that fairness, fatally infected the trial; the acts complained of must be of such quality as necessarily prevent a fair trial.” Lisenba v. California, 314 U.S. 219, 236, 62 S.Ct. 280, 290, 86 L.Ed. 166 (1941) (emphasis added).
Few defendants, however, will succeed in demonstrating on collateral review that their prosecutions merited such condemnation. As the Supreme Court has recently reminded us, “Beyond the specific guarantees enumerated in the Bill of Rights, the Due Process Clause has limited operation. We, therefore, have defined the category of infractions that violate ‘fundamental fairness’ very narrowly.” Dowling v. United States, 493 U.S. 342, 352, 110 S.Ct. 668, 674, 107 L.Ed.2d 708 (1990). Heeding this admonition, we adopt a particularly cautious approach to granting habeas relief for cumulative errors. “Cumulative error” is an infinitely expandable concept that, allowed to run amok, could easily swallow the jurisprudence construing the specific guarantees of the Bill of Rights and determining minimum standards of procedural due process. Under its aegis, an error that would not have risen to constitutional dimension by itself might suddenly, when aggregated with other non-constitutional errors, become worthy of habeas relief. The legal certainty afforded by rules drawn from the specific Bill of Rights provisions related to criminal law could then yield to the subjectivity of fundamental [1458]*1458fairness determinations. Worse yet, a free-floating fundamental fairness rule subverts the uniformity of results that is the basic goal of an organized legal system: one defendant may persuade the court that his five non-constitutional errors denied fundamental fairness, while another, less imaginative, may be denied relief simply because he cited only four of the same errors out of the record.
Equally important, granting habeas relief from state convictions for aggregated non-constitutional errors may too easily conflict with established limits on the scope of federal habeas relief. That result would thwart recent decisions that emphasize due regard for the finality of state court judgments. See, e.g., Coleman v. Thompson, — U.S. —, —, 111 S.Ct. 2546, 2563, 115 L.Ed.2d 640 (1991); McCleskey v. Zant, — U.S. —, —-—, 111 S.Ct. 1454, 1468-69, 113 L.Ed.2d 517 (1991); Teague v. Lane, 489 U.S. 288, 309, 109 S.Ct. 1060, 1074, 103 L.Ed.2d 334 (1989). To avert such a conflict, while recognizing that formulating a complete definition of unconstitutional cumulative error is not feasible, we can at least eliminate certain types of complaints that should generally not be considered in cumulative error review. By this process of elimination, minimum standards at least normally applicable to a cumulative error claim of constitutional dimension may be expressed.
First, any cumulative error theory must refer only to errors committed in the state trial court. A habeas petitioner may not just complain of unfavorable rulings or events in the effort to cumulate errors. See United States v. Rivera, 900 F.2d 1462, 1470-71 (10th Cir.1990) (en banc); Mullen v. Blackburn, 808 F.2d 1143, 1147 (5th Cir.1987) (“Twenty times zero equals zero.”). If an action of the trial court cured a putative error, the petitioner is complaining only of an adverse event rather than actual error. Compare Donnelly, 416 U.S. at 645, 94 S.Ct. at 1872.
Second, the error complained of must not have been procedurally barred from habeas corpus review. See, e.g., Coleman v. Thompson, supra. Beyond the notion of procedural bar, it is important that a defendant objected to errors to demonstrate that they were believed at the time of trial to have had an adverse effect on the defense. A trial transcript is lifeless, bereft of the nuances of behavior, facial expression and inflection of voice that so powerfully influence the participants and jury. A transcript may be misleading: it may suggest for instance, that the trial judge made a comment arguably demeaning to the defendant, although the judge actually intended to display wry humor or to mutter to himself rather than reprove the defendant. Only a contemporaneous objection, difficult as it may be to criticize comments by the judge or opposing counsel’s argument, distinguishes harmless remarks from those truly felt to be prejudicial to the defense.
Third, errors of state law, including evidentiary errors, are not cognizable in habeas corpus as such. Estelle v. McGuire, — U.S. —, —, 112 S.Ct. 475, 480, 116 L.Ed.2d 385 (1991); Marshall v. Lonberger, 459 U.S. 422, 438 n. 6, 103 S.Ct. 843, 853 n. 6, 74 L.Ed.2d 646 (1983). Errors of state law rise to constitutional dimension only if they “so infused the trial with unfairness as to deny due process of law.” Lisenba v. California, 314 U.S. 219, 228, 62 S.Ct. 280, 286, 86 L.Ed. 166 (1941); see also Walker v. Engle, supra.
Fourth, the federal court must review the record as a whole to determine whether the errors more likely than not caused a suspect verdict. Kirkpatrick v. Blackburn, 777 F.2d 272, 281 (5th Cir.1985), cert. denied, 476 U.S. 1178, 106 S.Ct. 2907, 90 L.Ed.2d 993 (1986).
This case vividly demonstrates the shortcomings of free-range cumulative error analysis. The errors regarded as heavily prejudicial by the panel majority either did not involve “errors” so much as adverse events, or were not preserved by objection in the trial court, or concerned state law rather than constitutional questions. Significantly, they were not outcome-determinative. Derden’s claims transgress nearly all of the limits that [1459]*1459must circumscribe cumulative error review for federal habeas corpus purposes.
Derden alleged three sources of “error” that allegedly poisoned the atmosphere of his trial: comments by the trial court; two instances of prosecutorial misconduct; and a Brady violation. The record does not, however, confirm the baleful influence that Derden attributes to these events.
A. The Judge
The conduct of a trial judge can violate due process only if the judge so favors the prosecution that he appears to predispose the jury toward a finding of guilt or to take over the prosecutorial role. See United States v. Middlebrooks, 618 F.2d 273, 277 (5th Cir.), cert. denied, 449 U.S. 984, 101 S.Ct. 401, 66 L.Ed.2d 246 (1980); United States v. Sheldon, 544 F.2d 213, 219 (5th Cir.1976). Some of the comments by Derden’s trial judge were ambiguous or imprudent, but taken in the context of the entire, hotly contested trial, they did not deny due process. Derden did not make a single objection to the trial court’s allegedly inflammatory remarks.8
Taking the allegedly offensive judicial remarks one by one, Derden complains that the court admonished him not to look at the jury.9 At this point in his testimony, Der-den had begun a speech, wholly unresponsive to the prosecutor’s question, directly trying to appeal to the jury. Repeatedly; Derden’s responses to questioning by the prosecutor and his own attorney had been unresponsive and narrative. The court repeatedly cautioned Derden several times about this conduct. The judge had instructed Derden twice on the preceding page of the transcript, and at other times, to answer questions directly. The court’s exasperation is understandable, whether or n0^ particular instruction was appropriate.
Derden also objects to the court’s having sustained four objections to his attorney’s opening argument. The prosecutor’s opening argument had been extremely brief. Defense counsel could have summarized his contentions with similar brevity by saying that the co-conspirators were all lying, because their stories were completely inconsistent and each had received a deal from the prosecutor in order to “get” Derden. Instead, defense counsel embarked on a rambling preview of the likely evidence. Surely the judge was entitled to set some limits on opening remarks, both to maintain control of his courtroom and because attorneys’ statements are not evidence.
In this court, Derden recounts instances in which the trial judge admonished defense counsel in various ways during trial. Derden’s trial counsel neither objected to any of the sporadic comments in the trial court nor pointed them out specifically on appeal to the Mississippi Supreme Court. Under such circumstances, it is impossible to calculate the effect of such remarks on the jury.
Derden complains that the trial court responded to the prosecutor’s objection to the defendant’s closing argument by saying he did not hear defense counsel’s argument.10 Such candor might have been regrettable, but in the end, the court did not sustain the objection and defense counsel proceeded. [1460]*1460The record provides no context for this remark, and appellate counsel, not having served at trial, offer no elucidation.
Contrary to Derden’s overriding charges of trial court bias, the record reveals other instances in which the court aided defense counsel. The court insisted that the prosecutor obtain, for purposes of impeachment, records of Sherrod’s prior criminal activities that were not readily available to defense counsel. The court also allowed hearsay questioning by defense counsel during a preliminary hearing and at trial. On balance, the court ruled evenhandedly on both sides’ objections.
Federal courts are poorly situated to evaluate the “tone” of state court proceedings from the abstract vantage point of a trial transcript. Federal judicial officers are increasingly unlikely in this day and age to be personally acquainted with their state counterparts or with the lawyers who appeared at trial. We cannot impute vitriol or impropriety to comments that a record renders ambiguous. Reflecting this caution, we are persuaded that none of the judge’s comments is even an obvious abuse of discretion, much less that they acted cumulatively or in tandem with other events to poison the jury against Derden.
B. The Prosecutor
The standard for granting habeas relief because of prosecutorial misconduct is “the narrow one of due process, and not the broad exercise of supervisory power.” Darden v. Wainwright, 477 U.S. 168, 181, 106 S.Ct. 2464, 2471, 91 L.Ed.2d 144 (1986). As we have noted, “federal courts may not, in a habeas corpus proceeding, impose the same standards upon state prosecutors that they apply to federal prosecutors in cases on direct appeal.” Kirkpatrick, 777 F.2d at 281. Derden pointed out two violations of Mississippi law by the prosecutor, both of which were corrected by the trial court. The prosecutor admittedly overstepped his bounds under Mississippi law when in voir dire he tried to commit the jury to evaluate the co-conspirators’ testimony like any other. This state law error, the State Supreme Court held, would have been reversible if the trial court had not properly instructed the jury at the end of trial to beware of such testimony. Derden, 522 So.2d at 754-55. The prosecutor also erred under Mississippi law in eliciting from Sherrod that Derden was his accomplice in other robberies. But this misstep was immediately corrected by the trial court’s instruction to the jury to disregard that evidence. Derden did not move for a mistrial. If Derden had been tried in federal court, a violation of Federal Rule of Evidence 404(b) might have occurred — neither a constitutional error nor reversible in itself, particularly because of the trial court’s prompt curative instruction. See e.g., Woodruff v. Lane, 818 F.2d 1369, 1373 (7th Cir.1987); Sargent v. Armontrout, 841 F.2d 220, 224 (8th Cir.1988). Under Estelle, supra, these violations of state law were not of a constitutional dimension, and it defies logic to suggest that the prosecutor who committed them behaved in an unconstitutionally prejudicial way.
C. The Brady Violation
The prosecutor’s alleged Brady11 violation likewise furnishes no assistance to Derden. He contended that the prosecution withheld evidence of the police radio log that showed that no radio call was made on the Wade’s Grocery Store burglary until 2:00 a.m. Derden argues that the radio log conflicted with and would have impeached the co-conspirators’ testimony that the burglary occurred between. 12:00 and 1:00 a.m. It is not clear, however, that such evidence would have been exculpatory. The police might have acted on their report slowly. Other witnesses timed the burglary between 12:00 and 1:00 a.m. If the co-conspirators’ and witnesses’ sense of the time was incorrect, that does not cast doubt that a burglary occurred, nor does it demonstrate in any greater degree that the other burglars fabricated Derden’s involvement. We disagree that the evidence on police call sheets was material or exculpatory, as a Brady claim requires.
[1461]*1461D. The “Cumulative” Impact
Because there were no trial court errors' that affected Derden’s specific constitutional rights, and few that were properly preserved by objection, the “error” predicate for a cumulative error habeas corpus theory dissolves. Even if the events of which Derden complains were “errors,” it cannot reasonably be said that they cumulatively so infected the trial with unfairness as to render his conviction a denial of due process. Co-conspirator testimony should indeed be suspect and viewed with caution, as the trial court instructed the jury, but here, the jury was fully aware of the favorable treatment the other burglars had received from the prosecutors.. Further, Turner and Posey testified that they gave the prosecutor statements implicating Derden in the burglary before any plea bargain was reached. The inconsistencies in the co-conspirators’ testimony related only to the timing of events the night of the burglary. Derden’s alibi was demonstrably weak and unsupported by any disinterested testimony. He was stopped while driving his van in the wee hours of February 10 and ticketed for having broken tail lights. In the swearing match between Derden and his defense witnesses and the co-conspirators, the jury could readily have believed the co-conspirators. Had none of the events of which Derden now complains occurred, it is almost certain that he would have been convicted of burglary.
Derden’s habeas case, rather than crying out for the federal courts to curb a state judicial system run amok, evokes that endless multiplication of claims disparaged by this court in Mullen, 808 F.2d at 1147. Derden’s assembly of cumulative errors has varied kaleidoscopically as he proceeded through state and federal review of his conviction. In the state court, he complained of a fundamentally unfair pretrial hearing, of the erroneous admission of hearsay testimony, and the violation of Pam Smith’s fifth amendment rights as among the errors contributing to a due process violation. In the federal courts, however, he abandoned those points but beefed up the number of instances of alleged judicial bias. Several of his complaints of judicial misconduct have never been proffered to the Mississippi courts, by objection or otherwise. His mutating claims represent the logical conclusion of a process of seeking “fundamental fairness” unconstrained by standards or limits.
In concluding that Derden’s right to due process was not violated by the Mississippi state court, we need not disagree that some errors were committed. Whether considered individually or cumulatively, however, the trial errors did not assume constitutional significance, and we are led to the conclusion that if Derden’s trial was in some ways procedurally imperfect, it was by no means fundamentally unfair.. Lundy, 888 F.2d at 481. Delaware v. Van Arsdall, 475 U.S. 673, 681, 106 S.Ct. 1431, 1436, 89 L.Ed.2d 674 (1986). Cumulative error in habeas corpus review, a narrow and rare form of a due process violation, in no way applies to the facts before this court.
The judgment of the district court denying habeas corpus relief is AFFIRMED.
