James Eric Mansfield appeals the denial of his petition for habeas corpus relief under 28 U.S.C. § 2254. We affirm.
I. BACKGROUND
Mansfield was convicted in Missouri state court of first-degree murder and armed criminal action for the stabbing death of Mark Trader. He was sentenced to two concurrent terms of life imprisonment.
Before trial, the state filed a motion in limine to exclude evidence that other people had a motive and an opportunity to commit the murder. Because there was no evidence directly linking the others to the crime, the trial court granted the motion. The case then proceeded to trial before a jury.
At trial, the state presented evidence showing that Mark Trader had been stabbed to death outside his apartment after an evening of drinking. The evidence centered around a group of regular patrons and employees of Papa Leone’s Italian Deli and Bar in Independence, Missouri (“the bar”). The state’s principal witness was John Hertlein, a friend of Mansfield, who testified to events that occurred on the night of the murder.
*1020Hertlein testified that he, Mansfield, and several others, including Mark Trader, had been drinking at the bar. After the establishment closed, one of their party called a cab for Mark Trader, who was too inebriated to drive. Mansfield assisted Trader into the cab and gave the cabdriver Trader’s address.
At that point, Hertlein and Mansfield drove to Trader’s apartment building in Mansfield’s car. On the way, Mansfield stated, “I’m going to Gerber him,”1 and then pulled a knife from under the seat of the car. When they arrived at Trader’s apartment, Mansfield confronted Trader outside the apartment building. After arguing for a few minutes, Trader and Mansfield walked to a place between the two apartment buildings where Hertlein could no longer see them. Hertlein testified that he overheard Trader say, “kill me” or “try and kill me,” and then heard thumping and gurgling sounds. Mansfield returned to the car with blood on his hands. Hertlein asked what had happened and Mansfield replied, “the first shot he took was in the Adam’s apple” and admitted that he had stabbed Trader ten to twenty times.
Hertlein then took the wheel and the two men returned to the bar, where they encountered Jon David Couzens. After talking to Couzens for a few minutes, Hertlein drove to a nearby gas station so that Mansfield could clean up. Because there were people present at the station, the two decided not to use the station’s restroom and drove instead to the apartment of Hertlein’s cousin, Angela Cascone, where Mansfield washed and borrowed a clean shirt. Mansfield then drove Hertlein back to the deli. Hertlein then went home.
The next day, Hertlein contacted the police and was brought to the police station, where he later gave a written statement and videotaped testimony outlining the night’s events. That same day, the police arrested Mansfield as he was leaving his home. Hertlein agreed to assist police officers by audiotaping a conversation with Mansfield in the hope that Mansfield would incriminate himself. Hertlein was placed in the cell next to Mansfield with two other men. Hertlein told his cell mates that he had been arrested for the murder of Mark Trader and stated that he had assisted in the murder. Mansfield made no incriminating statements in response.
Hertlein’s version of the night’s events was corroborated by several other witnesses. Jon David Couzens testified that Mansfield asked “why don’t I just go pop him?” before leaving Papa Leone’s with Hertlein and that Mansfield was holding a knife and had blood on his hands when he returned. A bar patron, Katherine Halsey, testified that she overheard Mansfield remark, “do you want me to pop him?” The cabdriver, Scott Blanz, identified Mansfield as one of the two men arguing outside Trader’s apartment.2 An elderly resident of the apartment building testified that she heard raised voices, followed by gurgling and then saw a male running from the scene. Jon David Couzens also testified that Mansfield stated, “we have a bond between us and this is to go no further, but Trader is dead, I killed him.” Hertlein testified that he overheard this remark. A gas station patron testified that he saw a car matching the description of Mansfield’s circling through the gas station. Hertlein’s cousin, Angela Cascone, testified that Hertlein asked if a friend could use her bathroom to clean up and that she later heard the water running. A police officer testified that physical evidence of blood was later found in Cas-cone’s sink. Another police officer sub*1021stantiated Hertlein’s testimony that he had been placed in a cell next to Mansfield to entice Mansfield into a confession.
Mansfield presented an alibi defense. Mansfield’s mother testified that he was home by 2:20 a.m. on the night of the murder. An expert testified that it would have been impossible for events to have occurred as Hertlein testified they did under the time sequence that had been presented. Mansfield also testified in his own defense and denied committing the murder.
Mansfield was convicted of murder in the first degree and armed criminal action. He filed a joint motion for a new trial and for post-conviction relief, which was denied by the trial court. He then jointly appealed his conviction and filed for post-conviction relief under Missouri Rule 29.15. The Missouri Court of Appeals affirmed his conviction and denied post-conviction relief, finding that Mansfield had not properly preserved his points for review. See State v. Mansfield, 891 S.W.2d 854, 855 (Mo.App.1995).
Mansfield then filed for habeas corpus relief in federal district court under 28 U.S.C. § 2254. He alleged violations of his Sixth Amendment right to adequate representation by counsel and violations of his Fifth Amendment right to due process of law. The state argued that Mansfield’s claims were procedurally barred. The district court found the claims were not procedurally barred, but nevertheless denied relief because it found that Mansfield had not shown that his counsel’s representation fell below an objective standard of reasonableness. The district court later denied Mansfield’s motion for a certificate of ap-pealability, finding that Mansfield had made no substantial showing of the denial of a constitutional right.
Mansfield moved for a certificate of ap-pealability in this court. We found that Mansfield had made a sufficient showing of the denial of his Sixth Amendment right to effective assistance by counsel in the following particulars: (1) counsel’s failure to develop and present evidence showing others were responsible for the murder; (2) counsel’s failure to effectively impeach the state’s chief witness with evidence that the witness had earlier implicated himself in the murder; and (3) counsel’s failure to object to the state’s cross-examination of defendant when the state asked defendant why the state’s witnesses were lying.
II. DISCUSSION
As a threshold matter, the state argues that Mansfield’s ineffective assistance of counsel claim is procedurally defaulted. It asserts that federal review is precluded because Missouri state courts relied on an adequate and independent state ground for its disposition of the case. Although we are inclined to agree with the district court that our review is not barred in this case, we need not reach this difficult question. Since we find that Mansfield cannot prevail on the merits, we see no need to belabor the procedural bar issue. See Barrett v. Acevedo, 169 F.3d 1155, 1162 (8th Cir.1999) (en banc) (stating that judicial economy sometimes dictates reaching the merits if the merits are easily resolvable against a petitioner and the procedural bar issues are complicated), cert. denied, — U.S. -, 120 S.Ct. 120, 145 L.Ed.2d 102 (1999).
Mansfield’s ineffective assistance claims center on his counsel’s failure to present evidence implicating Hertlein, Couzens, and another bar patron, J.R. Howerton, in the murder. The record shows that Mansfield’s counsel was prevented from presenting such a defense by the trial court’s ruling on the government’s motion in li-mine.3 In connection with that ruling, Mansfield contends that counsel was inef*1022fective in failing to present to the court a police report that stated that Hertlein had been overheard in jail bragging that he was responsible for the murder. The record shows that the report was obtained at the behest of Mansfield’s counsel, who asked that the police interview the prisoners who had shared a cell with Mansfield and Hertlein. Mansfield’s counsel was thus aware of the existence and contents of the report. Mansfield argues that, had this evidence been presented, the trial court would not have prevented him from mounting the defense that Couzens, Hert-lein and Howerton were responsible for the murder.
To prevail on his ineffective assistance of counsel claim, Mansfield must first show that his attorney’s performance fell below an objective standard of reasonableness and must further show that the deficient performance prejudiced his defense. See Strickland v. Washington, 466 U.S. 668, 687, 104 S.Ct. 2052, 80 L.Ed.2d 674 (1984). With respect to attorney performance, Mansfield must overcome the strong presumption that “the challenged action ‘might be considered sound trial strategy.’” Id. at 689, 104 S.Ct. 2052 (quoting Michel v. Louisiana, 350 U.S. 91, 101, 76 S.Ct. 158, 100 L.Ed. 83 (1955)). To show prejudice, Mansfield must establish a reasonable probability that he would have been acquitted absent the allegedly unprofessional error. See Strickland, 466 U.S. at 694, 104 S.Ct. 2052. We do not set aside a conviction or sentence solely because the outcome would have been different but for counsel’s error, rather, the focus is on whether “counsel’s deficient performance renders the result of the trial unreliable or the proceeding fundamentally unfair.” Lockhart v. Fretwell, 506 U.S. 364, 372, 113 S.Ct. 838, 122 L.Ed.2d 180 (1993).
The trial court granted the government’s motion in limine in reliance on State v. Umfrees, 433 S.W.2d 284, 287-88 (Mo.1968) (en banc).4 That case provides that evidence that another person had an opportunity or motive for committing the crime for which the defendant is being tried is not admissible “without proof that such other person committed some act directly connecting him with the crime” and evidence that clearly points to someone other than the accused as the guilty person. Id. at 288. Mansfield asserts that the police report furnishes such direct proof of others’ involvement.5
*1023We question the value of Mansfield’s purported evidence. In light of Hertlein’s testimony, corroborated by a police officer, that Hertlein had been “planted” in the cell next to Mansfield in order to obtain a taped confession, any admissions he made in the jail cell can be explained as part of the scheme to trick Mansfield into confessing. The report thus lacks any real probative value. In addition, we find the statements by the other prisoners are equivocal and contradictory. One prisoner stated that Hertlein said that “three of them” followed the cab and each one stabbed Trader. Another prisoner stated that Hertlein said that he had stabbed the victim and the others watched. Significantly, none of the statements exclude Mansfield as a perpetrator.
Most importantly, the police report only substantiates evidence that the trial court actually heard. Hertlein himself testified that he had made the admissions at the jail. The trial court heard the substance of the evidence that supposedly incriminated others and could have reversed its ruling on the motion in limine had it been inclined to do so.
We are not convinced that the police report amounts to evidence that satisfies the Umfrees standard. Mansfield’s purported evidence would show only that he either aided or was aided by others in the murder, or that he committed the murder at the behest of others. It does not point to others as the guilty persons to the exclusion of Mansfield. We thus find it doubtful that the presentation of this evidence would have caused a contrary ruling by the trial court.
Thus, we find Mansfield’s counsel’s failure to present this evidence to the court was not objectively unreasonable. Counsel may have had compelling strategic reasons for his failure to press the evidence upon the court. Counsel could have reasonably assumed that the evidence was damaging to Mansfield’s case, in that it undermined his alibi defense. The statements also could have been viewed as damaging in that they provided further corroboration of Hertlein’s version of events. The evidence lacked any real benefit to Mansfield because it was “explained away” by Hertlein’s testimony that the statements were part of a ruse to get Mansfield to confess.
Moreover, even if Mansfield were able to show that his counsel’s actions were objectively unreasonable, he is unable to show prejudice. Contrary to Mansfield’s assertions, the state’s case against him was not weak.6 The damaging testimony by Hertlein was corroborated by the testimony of several others, most importantly, the cabdriver. Although the cabdriver later faltered in his identification of Mansfield by testifying at trial that the perpetrator had a mustache, Mansfield’s counsel pointed the inconsistency out in closing argument. We have reviewed the record and find that Mansfield has not shown that the result of his trial is unreliable or the proceeding was fundamentally unfair. We have considered Mansfield’s other arguments and find them lacking in merit.
To the extent that Mansfield contends he is actually innocent of this crime, *1024we add that a claim of “actual innocence” is not itself a constitutional claim, but instead a gateway through which a habeas petitioner must pass to have his otherwise barred constitutional claim considered on the merits. See Herrera v. Collins, 506 U.S. 390, 404, 113 S.Ct. 853, 122 L.Ed.2d 203 (1993). “[T]he traditional remedy for claims of innocence based on new evidence, discovered too late in the day to file a new trial motion, has been executive clemency.” Id. at 417, 113 S.Ct. 853.
III. CONCLUSION
The district court’s denial of Mansfield’s petition for a writ of habeas corpus is affirmed.
