    MICHAEL BRANDON SAMRA,
    Petitioner - Appellant,

    Respondent - Appellee.
    ________________________
    Appeal from the United States District Court
    for the Northern District of Alabama
    ________________________
    (September 8, 2015)
    Before ED CARNES, Chief Judge, and HULL and ROSENBAUM, Circuit Judges.
    PER CURIAM:
    Petitioner-Appellant Michael Brandon Samra was convicted and sentenced
    to death by an Alabama court in 1998 for the murders of four people, including
    Case: 14-14869     Date Filed: 09/08/2015   Page: 2 of 42
    two children. Samra’s conviction and sentence were upheld on direct appeal, and
    the Alabama state courts rejected his claims for postconviction relief. Samra
    sought federal habeas relief under 28 U.S.C. § 2254, but the district court denied
    Samra’s federal petition. Samra now appeals raising two issues. First, Samra
    argues that his trial counsel was ineffective for failing to investigate evidence of
    brain dysfunction and for introducing and emphasizing evidence of Samra’s
    membership in a Satanic gang, which he contends strengthened the state’s
    aggravation case. Second, Samra asserts that his appellate counsel was ineffective
    for not raising an argument on appeal that Samra was entitled to pretrial notice of
    the specific statutory aggravating factor that the state intended to rely upon in
    pursuing the death penalty. After a thorough review of the record, and with the
    benefit of oral argument, we now affirm the denial of Samra’s federal habeas
    petition.
    I.
    A. The Criminal Offense
    Samra was convicted of capital murder, in violation of Alabama Code §
    13A-5-40(a)(10), and he was sentenced to death for his role in the killings of
    Randy Duke, Dedra Hunt, Chelsea Hunt, and Chelisa Hunt.         See Samra v. State
    (Samra Direct Appeal), 
    771 So. 2d 1108
    , 1111-12 (Ala. Crim. App. 1999); Samra
    v. Price (Samra § 2254 Proceeding), No. 2:07-cv-1962-LSC,

    at *1 (N.D. Ala. Sept. 5, 2014). According to the evidence established at trial and
    by Samra’s own confession, Randy Duke’s sixteen-year-old son Mark Anthony
    Duke (“Duke”) devised the murder following an argument where Randy Duke
    refused to allow Duke to use a pickup truck. Samra § 2254 Proceeding, 
    2014 WL 4452676
    , at *1. After planning the murder with Samra and two other friends,
    David Collums and Michael Ellison, the group obtained two guns and returned to
    Duke’s house. Samra § 2254 Proceeding, 
    2014 WL 4452676
    , at *1. Samra and
    Duke entered the house while Collums and Ellison waited nearby. 
    Id. Once inside,
    Duke went to the living room and shot his father, killing him.
    Samra § 2254 Proceeding, 
    2014 WL 4452676
    , at *1. Meanwhile, Samra shot
    Dedra1 non-fatally in the cheek, and she fled upstairs, locking herself in the master
    bedroom’s bathroom with her six-year-old daughter Chelisa.                  Samra Direct

    Duke broke down the bathroom door and shot Dedra to death. Samra § 2254

    Duke went downstairs to retrieve kitchen knives; he then slit Chelisa’s throat with
    a kitchen knife. 
    Id. Dedra’s seven-year-old
    daughter Chelsea was hiding under a
    bed in another bedroom when Duke found her. Samra § 2254 Proceeding, 
    2014 WL 4452676

    stop and, as also evidenced by the defensive wounds on her body, vigorously
    fought for her life. Samra § 2254 Proceeding, 
    2014 WL 4452676
    , at *1. Unable
    to kill her by himself, Duke held Chelsea down while Samra slit her throat. Samra

    , at *1; Samra Direct 
    Appeal, 771 So. 2d at 1112
    . According to the testimony of the medical examiner, both girls died as a
    result of drowning in their own blood.
    After committing the murders, Samra and Duke ransacked the house to
    make it appear as though a burglary had gone wrong. Samra § 2254 Proceeding,
    
    2014 WL 4452676
    , at *1. Duke later returned to his house on March 23, 1997,
    where he called 911 to report the murders. After a couple of days of investigating,
    the police determined that Duke, Samra, Collums, and Ellison were the
    perpetrators. Samra confessed his role in the crime during questioning and assisted
    police in recovering weapons. See Samra § 2254 Proceeding, 
    2014 WL 4452676
    ,
    at *1.
    B. Trial Proceedings
    Samra was indicted for the four murders under § 13A-5-40(a)(10), Ala.
    Code, which makes it a capital crime when “two or more persons are murdered by
    the defendant by one act or pursuant to one scheme or course of conduct.” Samra
    Direct 
    Appeal, 771 So. 2d at 1111
    . The indictment itself was a single paragraph
    listing the victims’ names and the weapons used to kill them. Later, the indictment
    4
    Case: 14-14869    Date Filed: 09/08/2015   Page: 5 of 42
    was amended to add an aiding-and-abetting component and to clarify that Dedra
    Hunt was killed with a gun. The indictment did not describe any further details of
    the crime, and it did not specify any of the then-existing statutory aggravating
    circumstances under § 13A-5-49, Ala. Code, that would permit imposition of the
    death penalty.
    Samra was represented at trial and on appeal primarily by appointed counsel
    Richard Bell, an experienced attorney who devoted approximately 35 to 40 percent
    of his practice to criminal-defense work and had defended three capital cases prior
    to Samra’s. Samra § 2254 Proceeding, 
    2014 WL 4452676
    , at *2. Based on his
    initial investigations and interactions with Samra, Bell decided that his defense
    strategy needed to focus on Samra’s mental condition and the influence of gang
    membership on Samra’s actions. Samra § 2254 Proceeding, 
    2014 WL 4452676
    , at
    *2. Bell concluded, though, that Samra had only “a very small chance of winning
    the guilt phase,” and that the sentencing phase would be the main event. See Vol.
    39 at 183.
    Before trial, Bell filed a motion to compel the state to disclose the
    aggravating circumstances upon which it intended to rely in seeking a death
    sentence, arguing that Samra needed to be informed of the aggravating factors that
    the state intended to prove in order to prepare for the sentence hearing. Samra §
    2254 Proceeding, 
    2014 WL 4452676
    , at *2. The state argued that it was not
    5
    Case: 14-14869     Date Filed: 09/08/2015     Page: 6 of 42
    required to reveal this information prior to the sentencing phase but that in any
    event, “the aggravating circumstances are very straight forward in the indictment.”
    Samra § 2254 Proceeding, 
    2014 WL 4452676
    , at *2. The court denied Samra’s
    motion, noting that the statute sets forth a very “limited” and “particularized” set of
    aggravating factors.
    With respect to Samra’s mental condition, Bell enlisted the expertise of Dr.
    Charles Scott, a forensic psychiatrist.        Samra § 2254 Proceeding, 
    2014 WL 4452676
    , at *2.        Dr. Scott prepared a 21-page report based on a six-hour
    psychiatric interview with Samra, an interview with Samra’s parents, and a review
    of Samra’s school and medical records. 
    Id. Based on
    these interviews and records,
    Scott concluded that Samra was not suffering from a mental illness or defect that
    precluded him from distinguishing right from wrong and that he appreciated the
    wrongfulness of his conduct.         In light of Samra’s history and Dr. Scott’s
    interactions with Samra, Dr. Scott recommended to Bell that Samra undergo “a
    complete neuropsychological evaluation, neurology consultation and brain
    imaging,” either through a SPECT or PET2 scan, or if those tests were unavailable,
    at least an MRI or x-ray. See Samra § 2254 Proceeding, 
    2014 WL 4452676
    , at
    2
    “SPECT” stands for single-photon emission computed tomography, a method for
    imaging the function of internal organs, including blood flow to the brain. Tests and
    Procedures: SPECT Scan, MAYO CLINIC (Feb. 20, 2014), http://www.mayoclinic.org/tests-
    procedures/spect-scan/basics/definition/prc-20020674. “PET” stands for positron emission
    tomography, a similar function-imaging procedure. Tests and Procedures: Positron Emission

    Case: 14-14869       Date Filed: 09/08/2015      Page: 7 of 42
    *2.3 Dr. Scott’s report noted that his “preliminary opinion” of Samra’s culpability
    could change based on the results of these tests.
    In accordance with Dr. Scott’s recommendation, Bell obtained an MRI of
    Samra’s brain. It showed no structural abnormalities. Bell did not procure a
    SPECT or PET scan. 4 Samra § 2254 Proceeding, 
    2014 WL 4452676
    , at *2.
    Ultimately, Bell chose not to present Dr. Scott as a witness since he believed that
    Dr. Scott’s testimony would be unfavorable to Samra. Samra § 2254 Proceeding,
    
    2014 WL 4452676
    , at *2.
    Because Bell had no evidence of brain dysfunction or mental disease and
    could not suppress Samra’s confession, he rested his guilt-phase trial strategy on
    Samra’s gang membership. As Bell explained, “Frankly . . . it appeared that that
    was the only thing I had.” Bell began laying the groundwork for this strategy
    during voir dire and in his opening statement, referring to Samra’s and Duke’s
    membership in the Forever Our Lord King Satan (“FOLKS”) gang.
    3
    Dr. Scott’s report listed as examples of types of brain imaging only MRI or PET
    scanning. Bell testified during the state postconviction hearing that Dr. Scott had also
    recommended to him obtaining a SPECT scan. The SPECT scan was also mentioned in an
    affidavit that Bell prepared on Dr. Scott’s behalf but was never signed by Dr. Scott. Although
    the state contends, correctly, that Dr. Scott’s report did not mention a SPECT scan, the record
    supports Samra’s claims that Dr. Scott did otherwise recommend a SPECT scan to Bell.

    Case: 14-14869   Date Filed: 09/08/2015    Page: 8 of 42
    During trial, the prosecution introduced photos and video recordings of the
    walls in Duke’s bedroom, which had various symbols and words carved into them.
    These etchings included Samra’s nickname, “Baby D.”               At one point, the
    prosecutor described Duke’s room as having “gang-type writings” in it. During
    cross-examination of multiple police witnesses at trial, Bell emphasized the
    etchings and their affiliation with FOLKS and a “gang within a gang” known as
    the “Insane Gangster Disciples.” Photos of Samra’s tattoos were also admitted into
    evidence, although it is not clear if they were ever identified as gang-related.
    The defense called three witnesses during the guilt-phase of the trial. Dr.
    Kathleen Ronan, a clinical psychologist at the state’s Taylor Hardin Secure
    Medical Facility, testified that she had been ordered by the court to evaluate
    Samra’s competency to stand trial and his mental state at the time of the murders.
    Samra § 2254 Proceeding, 
    2014 WL 4452676
    , at *3. Dr. Ronan conducted a
    background interview, a mental status exam, a personality inventory, a discussion
    of the crime, and a trial-competency assessment. Vol. 13 at 19-20. Although Dr.
    Ronan did not perform a full IQ test, she testified that Samra possessed borderline
    intelligence based on her screening and the results of a test performed by another
    psychologist.    She also opined that Samra displayed signs of depression and
    anxiety, had internal conflicts about being dependent on others, was “insecure in
    8
    Case: 14-14869   Date Filed: 09/08/2015   Page: 9 of 42
    his interpersonal interactions,” and could become confused during periods of high
    stress.
    In addition, Dr. Ronan also testified that Samra told her he was affiliated
    with the FOLKS gang. The prosecutor then interrupted Bell’s questioning to point
    out that the gang question opened the door, allowing the prosecutor to present Dr.
    Ronan’s opinion that the murders had nothing to do with the gang membership,
    testimony the prosecutor conceded was otherwise inadmissible.                   Bell
    acknowledged that he understood that the prosecutor would ask that question, and
    the court also commented that it “underst[ood] all of that could be very appropriate
    strategy.”
    On cross examination, Dr. Ronan testified that she concluded Samra was
    competent to stand trial and that she found no evidence of any psychiatric disorder
    or mental disease that rendered him out of touch with reality or that impaired his
    sense of right and wrong. Samra § 2254 Proceeding, 
    2014 WL 4452676
    , at *3.
    She also testified that there was no evidence that Samra acted under duress or
    under the substantial domination of anyone at the time of the offense.           The
    prosecutor asked Dr. Ronan what Samra told her about the connection between his
    gang membership and the murders, to which she answered that Samra said the
    9
    Case: 14-14869        Date Filed: 09/08/2015       Page: 10 of 42
    killings had nothing to with the gang.5 Dr. Ronan also testified that Samra had a
    lack of emotionality when recounting the killings and that, based on the
    information available, she would “lean towards” that being indicative of antisocial
    personality disorder rather than emotional repression.
    The defense’s second witness was Dr. George Twente, a licensed
    psychiatrist. Samra § 2254 Proceeding, 
    2014 WL 4452676
    , at *3. Dr. Twente
    testified that he had studied the FOLKS gang, which he described as a close-knit
    drug-distribution organization that offered its members a sense of identity,
    belonging, and excitement. Dr. Twente also testified that to rise in the ranks of the
    gang, a member had to commit various illegal activities, and to rise to the highest
    level of “Set King,” he had heard a rumor that the member was required to kill his
    own mother. Dr. Twente confirmed that the symbols found in Duke’s bedroom
    were similar to symbols used by other FOLKS affiliates.                      According to Dr.
    Twente, if a member wanted to leave the gang he was told that he or a family
    member would be killed, but in Dr. Twente’s experience, nothing bad ever actually
    happened to members who left the gang. Dr. Twente asserted that usually gang
    killings were over territory or drugs, or they were retaliation for insults. Finally,
    5
    Before the prosecutor asked this question, he asked for a bench conference to find out if
    Bell would object. Bell said he would object because he did not think that asking about Samra’s
    gang affiliation opened the door to Samra’s statements about whether the killings were related to
    that affiliation. The court overruled the objection and permitted the state to ask Dr. Ronan a
    single question about what Samra told her about the killings’ relation to gang membership.
    10
    Case: 14-14869       Date Filed: 09/08/2015   Page: 11 of 42
    Dr. Twente conceded that he had never spoken with Samra nor made any
    determination whether these killings were in any way gang related.
    Samra’s final witness was Sara Woodruff, a FOLKS member and friend of
    Samra, Duke, Collums, and Ellison. She commented that Samra was her “least
    favorite” because he wasn’t “all there,” although he could carry on normal
    conversations with her. Woodruff testified that Duke told her about the killings.
    On cross examination, she stated that Samra and Duke were good friends who got
    along well, and the local “gang” consisted basically of the four boys and her. With
    respect to the night that Duke told her about the killings, Woodruff observed no
    indication of hostility or threat between Duke and Samra, and she thought that they
    were friendly to each other. She also added that Duke said that the killings were
    about a dispute he had with his father and that he did not tell her it had anything to
    do with the gang, although Duke did make her swear an oath before he discussed
    the killings with her.
    On March 16, 1998, the jury returned a verdict of guilty on the charges of
    capital murder. Following a half-hour recess after receiving the verdict, the court
    began the sentencing phase of the trial. At this point, the state confirmed that it
    was pursuing the eighth statutory aggravating factor under § 13A-5-49, Ala.
    Code—that the offense was especially heinous, atrocious, or cruel—to justify
    imposition of a death sentence.
    11
    Case: 14-14869     Date Filed: 09/08/2015   Page: 12 of 42
    The evidence introduced during the guilt phase was adopted for the
    sentencing phase. The state called a single witness, Thomas Hunt, the father of the
    two girls and ex-husband of Dedra, who testified as to the impact of their murders
    on him.
    During the penalty phase, Bell’s strategy shifted towards humanizing Samra.
    The defense called three members of Samra’s family: his aunt, his father, and his
    mother. The aunt testified that Samra was a loving and non-violent child. Samra’s
    father testified that, as a small child, Samra was developmentally slow and suffered
    tremors in his hands. His father testified that Samra was a good, obedient child
    until about 15 or 16 when he started using marijuana. His father then recounted
    various legal troubles Samra had concerning marijuana, until eventually he gave
    Samra an ultimatum: attend rehab for the marijuana use or leave the house. Samra
    moved out. Samra’s father stated that he suspected Samra was hanging around
    “gang-type people.”    His father also recalled that Samra had been in special
    education most of his life and eventually dropped out of high school. Finally, he
    noted that Samra was never really capable of expressing his emotions, but could
    still be loving.   Samra’s mother echoed his father’s testimony about Samra’s
    developmental difficulties and learning disabilities and his lack of emotionality.
    On the same day that the penalty phase began, March 16, 1998, the jury
    returned a unanimous verdict recommending death. Samra § 2254 Proceeding,
    12
    Case: 14-14869    Date Filed: 09/08/2015   Page: 13 of 42
    
    2014 WL 4452676
    , at *4. The court sentenced Samra to death on May 7, 1998.
    The court found that the sole aggravating circumstance proved was that the crime
    was especially heinous, atrocious, or cruel as compared to other capital offenses.
    The court determined that two of seven statutory mitigating factors existed: a lack
    of significant criminal history and Samra’s age (nineteen) at the time of the
    offense.   Ala. Code § 13A-5-51.      In addition, the court concluded that the
    following non-statutory mitigating factors existed “to some degree” and were
    “worthy of consideration in the weighing of mitigating circumstances and
    aggravating circumstances”: Samra’s age and maturity; learning difficulties and
    disabilities; “family history and background and caring nature of Defendant”; “the
    effect of gang or group involvement upon Defendant”; Samra’s cooperation and
    truthfulness with law enforcement; Samra’s remorse; and the existence of only a
    solitary aggravating factor. The court nevertheless found that “when weighed
    against the many mitigating circumstances, both statutory and non-statutory, the
    aggravating circumstance substantially outweighs the mitigating circumstances,”
    and imposed a sentence of death by electrocution.

    C. Direct Appeals
    Samra raised several issues on direct appeal, including a claim of ineffective
    assistance of trial counsel6 for failing to investigate whether Samra “suffered from
    any neurological or organic mental disease or defect that would have rendered him
    unable to appreciate the nature and quality or wrongfulness of his acts at the time
    of the offense.” Samra Direct 
    Appeal, 771 So. 2d at 1119
    . Samra also argued that
    counsel was ineffective for failing to adequately prepare a defense that Samra was
    not guilty by reason of mental disease or defect. 
    Id. The Alabama
    Court of
    Criminal Appeals (“ACCA”) rejected the ineffective-trial-counsel claim, finding
    that Samra failed to support it with evidence but that, in any event, counsel
    “adequately investigated the appellant’s competence and sanity.” 
    Id. at 1120.
    Samra’s counsel did not raise on direct appeal the argument rejected by the
    trial court that Samra was entitled to advance notice of which statutory aggravating
    factors the state planned to rely on to support the death penalty.
    The ACCA affirmed the death sentence. Samra Direct 
    Appeal, 771 So. 2d at 1121-22
    . After finding no plain error and agreeing that the evidence supported
    the death sentence, the Alabama Supreme Court affirmed. Ex parte Samra, 
    771 So. 2d 1122
    , 1122 (Ala. 2000). The United States Supreme Court denied certiorari

    Samra was represented by Bell on appeal with respect to all of his claims except the
    ineffective-assistance claim. The court appointed a separate attorney to argue that claim. See

    , 
    121 S. Ct. 317

    D. State Collateral Proceedings
    Samra filed a state petition for postconviction relief under Rule 32 of the
    Alabama Rules of Criminal Procedure on October 1, 2001. The petition was
    amended three times, with the final petition being filed on August 16, 2002. Of the
    claims advanced in his Rule 32 petition, the following ones are relevant here:
    (1) Samra was denied effective assistance of trial counsel during the penalty
    phase because of counsel’s “failure to adequately investigate organic brain
    damage/brain dysfunction.”
    (2) Trial counsel during the penalty phase “was ineffective for presenting
    mitigating evidence that was actually aggravating,” citing counsel’s repeated
    references to Samra’s membership in a Satanic gang.
    (3) Trial counsel was ineffective for “failing to adequately object to the
    admission of pictures of wall etchings, ‘gang-type’ writings, and tattoos on Mr.
    Samra’s arms.”
    (4) Appellate counsel was ineffective for arguing that Samra’s death
    sentence “violates the due process clause of the Fourteenth Amendment because
    the petitioner did not receive notice of the actual statutory aggravating
    15
    Case: 14-14869     Date Filed: 09/08/2015   Page: 16 of 42
    circumstance used at the sentencing phase, until after he had already been
    convicted of capital murder.”
    The Rule 32 court held a hearing on the brain-dysfunction claim. See Samra
    § 2254 Proceeding, 
    2014 WL 4452676
    , at *5. During the hearing, Samra called
    two medical witnesses and two attorney witnesses, including Bell. Bell testified
    that he did not obtain a SPECT test because he was told none were available in
    Birmingham, Alabama, and the closest machine was located in Nashville,
    Tennessee. Bell also submitted an affidavit stating that he did not request that
    Samra be transferred out of state for SPECT or PET testing. Although Bell
    recognized that a SPECT scan showing abnormalities could have been used as
    mitigating evidence, he testified that he did not obtain further neuropsychological
    testing on Samra because, “The neuropsychologist that we had contacted I believe
    stated that he would not or could not for some reason that I really don’t know what
    the reasons were that he could not do the testing of our client.” In addition, Bell
    attested that no further neuropsychological testing was conducted because Bell
    “believed Dr. Scott’s psychiatric examination covered this area.”
    Dr.   Michael     Gelbort,    a   clinical   psychologist     specializing   in
    neuropsychology, also testified at the Rule 32 hearing. Dr. Gelbort performed a
    neuropsychological evaluation on Samra in 2002. His evaluation established that
    Samra possessed a verbal IQ of 79 (11-12th percentile), a nonverbal IQ of 87 (40th
    16
    Case: 14-14869      Date Filed: 09/08/2015      Page: 17 of 42
    percentile),7 and a full-scale IQ of 81. Dr. Gelbort gave Samra the Categories Test,
    a test that measures “primarily frontal lobe and whole brain functioning.” Samra
    made 51 errors, placing him on the “cusp” between normal and brain impaired. As
    for Samra’s reading and math abilities, Dr. Gelbort found them to be in the 30th
    and 19th percentiles, respectively. On the Trailmaking test, which tests “cognitive
    flexibility and processing speed or efficiency,” Samra’s scores again placed him on
    the “cusp” between normal and slightly impaired. Samra’s scores on a memory
    test were also consistent with being on the line between average and mildly
    impaired. On the MMPI, which tests for gross psychopatholgy, Samra showed
    signs of mild depression but no signs of psychosis.
    Based on his clinical evaluations, Dr. Gelbort opined that Samra’s brain
    “would not be classified as normal or typical,” and that Samra possessed “some
    type of brain dysfunction.” Dr. Gelbort observed that this dysfunction “ha[d] more
    to do with verbally mediated skills as opposed to nonverbal or visual spatial
    skills.” Dr. Gelbort localized the dysfunction to the left side and frontal lobe,
    although he noted that there was no “focal damage” but “rather a diffuse pattern of
    dysfunction.” Ultimately, Dr. Gelbort concluded that Samra would have a more
    difficult time functioning than a normal person but that he was not “grossly
    impaired.” Dr. Gelbort also testified that he reviewed the testing results that the
    7
    This test was incomplete because the prison would not allow Dr. Gelbort to bring in
    certain equipment.
    17
    Case: 14-14869   Date Filed: 09/08/2015   Page: 18 of 42
    state’s expert, Dr. Glen King, had obtained and found those to be consistent with
    his own testing.
    Besides these witnesses, Samra presented the testimony of Dr. James
    Mountz, a specialist in nuclear medicine and radiology. Between 1991 and 2003,
    Dr. Mountz was at the University of Alabama—Birmingham (“UAB”) where he
    “built up” the “functional brain imaging protocols.” Dr. Mountz testified that a
    dual-head camera SPECT machine was available at UAB at least by the time he
    arrived there in late 1990, and possibly as early as 1988. A PET scan was not
    available at UAB, however, until July 2001.
    Dr. Mountz testified that a SPECT scan, as relevant to this case, measures
    blood flow in the brain. As Dr. Mountz explained SPECT scans, a SPECT scan
    does not distinguish between a normal and an abnormal brain but rather between
    normal and abnormal blood flow. Dr. Mountz also distinguished a SPECT scan
    from an MRI, in that an MRI measures anatomical structure while the SPECT scan
    measures blood flow to those structures; “function as opposed to structure.” He
    further explained that an MRI may show a normal structure, but a decreased blood
    flow may lead to abnormal brain functioning.
    Dr. Mountz conducted a SPECT scan on Samra on August 1, 2002. From
    the scan, Dr. Mountz concluded that “[t]here were areas of decreased blood flow
    which were abnormal.” Dr. Mountz testified to two basic abnormalities: one that
    18
    Case: 14-14869    Date Filed: 09/08/2015   Page: 19 of 42
    “falls into the milder category” and could just constitute normal variability, and a
    second “obvious abnormality in blood flow to the posterior frontal superior
    temporal region” of the right side of Samra’s brain. Dr. Mountz did not reach an
    opinion about Samra’s brain function but did opine that his brain blood flow was
    about one standard deviation below normal. He later characterized the blood flow
    as “low normal.” In a carefully worded answer, Dr. Mountz testified that the
    “abnormalities found in [Gelbort’s neuropsychological report] are not inconsistent
    with the brain SPECT scan” conducted on Samra. On cross examination, Dr.
    Mountz testified that a SPECT scan does not provide any insight into why a person
    commits murder or whether he can appreciate the wrongfulness of his conduct. He
    also testified that a more detailed analysis would be required to determine what
    functions the abnormal area controls in Samra’s specific case. Finally, Dr. Mountz
    also conceded that Samra’s brain scan could have looked much different in 1998.
    The state called two witnesses. The first, Dr. King, a clinical psychologist
    and attorney, conducted a neuropsychological evaluation of Samra. Dr. King
    performed an achievement test with Samra, where he scored Samra as reading at
    an eighth-grade level, spelling at a high-school level, and completing arithmetic at
    a sixth-grade level. According to Dr. King, an individual who has dropped out of
    school can be expected to score lower on these tests, as would an individual with a
    low IQ.
    19
    Case: 14-14869    Date Filed: 09/08/2015   Page: 20 of 42
    Dr. King administered an outdated IQ test, but the corrected results placed
    Samra’s full-scale IQ in the high borderline range of around 79 and his verbal and
    nonverbal IQ scores were consistent with what Dr. Gelbort found.            Samra
    performed well on some perceptual tests but poorly on others. His nondominant
    hand was weaker than expected, indicating “some lateralizing effect,” and his fine
    motor control was “below the cutoff.” Dr. King also concluded that Samra had
    some impairment in his visual-spatial area.
    Dr. King also administered the MMPI test. Consistent with Dr. Gelbort’s
    MMPI, Dr. King found that Samra suffered from mild depression and anxiety and
    immature interpersonal development but not any psychosis. Besides these tests,
    Dr. King administered the Categories Test, and Samra committed 52 errors,
    consistent with Dr. Gelbort’s testing and finding of mild impairment. Similarly,
    Samra scored slightly impaired on Dr. King’s Trailmaking test.
    As a result of his examinations, Dr. King concluded that Samra suffers from
    some impairment in his cognitive functioning. He further opined that at the time of
    the offense, Samra did not have any serious mental illness or mental defect that
    would have rendered him incapable of understanding the nature and consequences
    of his actions.   While acknowledging a debate among experts about whether
    someone with borderline or retarded intellectual ability suffers from brain
    impairment, Dr. King ultimately concluded that Samra “has impairment of
    20
    Case: 14-14869     Date Filed: 09/08/2015   Page: 21 of 42
    functioning that is consistent with what we would expect in someone who is in the
    borderline range of intellectual ability” but that this impairment did not impact
    Samra’s ability to appreciate the criminality of his conduct.
    Dr. Helen Mayberg, a neurologist, also testified for the state. She stated that
    the “generally accepted clinical uses of a SPECT technology are extremely
    limited,” and include diagnosing strokes, evaluating dementia, and identifying
    abnormalities associated with epilepsy, and identifying abnormalities following
    trauma. Like with any radiological procedure, Dr. Mayber explained, experience
    in evaluating SPECT scans is important in determining when a scan is “normal.”
    Dr. Mayberg reviewed Dr. Mountz’s report and found that it contained the
    typical elements of a SPECT report. According to Dr. Mayberg, though, one
    standard deviation was not abnormal but rather, still fell within the normal range.
    In Dr. Mayberg’s view, “brain damage” is too generalized a term, and the SPECT
    scan is too sensitive to blood-flow variation to make a good screening test for brain
    damage. Dr. Mayberg also reviewed Samra’s childhood records and speculated
    that he may have had a neurological problem as a child that improved over time.
    Finally, she agreed that Samra’s MRI from 1998 was normal.
    On January 12, 2005, the trial court denied Samra’s Rule 32 petition. See
    Samra § 2254 Proceeding, 
    2014 WL 4452676
    , at *9. With regard to the brain-
    dysfunction claim, the court held that Bell’s performance was not deficient as far
    21
    Case: 14-14869    Date Filed: 09/08/2015   Page: 22 of 42
    as investigating brain damage because he had pursued some investigation and had
    settled on another strategy. The court also determined that Samra suffered no
    prejudice because the results of Dr. Gelbort’s and Dr. Mountz’s testing only
    affirmed the information of Samra’s borderline intellectual abilities already before
    the jury. The court also rejected the idea that Samra suffered from any organic
    brain dysfunction. 
    Id. Nonetheless, the
    court added that even if Samra had
    reduced blood flow to his brain at the time of the offense, no evidence established
    that it would have affected Samra’s culpability, judgment, or insight. Further
    elaborating on prejudice, the trial court determined that no reasonable probability
    existed that the jury would have reached a different recommendation if Samra had
    presented Dr. Gelbort’s and Dr. Mountz’s evidence during the penalty phase of
    Samra’s trial.
    With respect to Samra’s argument that the gang evidence was more
    aggravating than mitigating, the Rule 32 court found that Bell’s strategy to portray
    Samra as gang-influenced was reasonable in light of the fact that Bell had no
    evidence of any other mental defect or prior history of violence.        The court
    determined that Samra’s argument about Bell’s failure to object to the admission of
    gang etchings and tattoos was “wholly without merit” because the evidence
    complemented Bell’s own defense strategy. Apparently, the Rule 32 court did not
    reach the prejudice prong of the ineffective-assistance analysis with respect to
    22
    Case: 14-14869     Date Filed: 09/08/2015   Page: 23 of 42
    these gang-related claims. The Rule 32 court also did not address the aspect of
    Samra’s due-process claim regarding notice of the aggravating factors; instead, it
    dealt with Samra’s related argument that Alabama’s sentencing procedure violated
    due process because it allows the judge to impose the sentence.
    On August 24, 2007, the ACCA affirmed the denial of postconviction relief.
    With respect to Samra’s due-process claim that he had not received notice of the
    aggravating factors, the ACCA determined that the claim failed on the merits
    because neither Apprendi v. New Jersey, 
    530 U.S. 466
    , 
    120 S. Ct. 2348
    (2000)—
    decided before Samra’s conviction became final—nor Ring v. Arizona, 
    536 U.S. 584
    , 
    122 S. Ct. 2428
    (2002)—decided after—“modified prior Alabama caselaw,
    ‘which holds that aggravating circumstances do not have to be alleged in the
    indictment.’”   And to the extent that Ring could be read to support Samra’s
    argument, the ACCA noted that it was decided two years after his conviction
    became final and that appellate counsel could not have been ineffective for failing
    to anticipate changes in the law.
    The ACCA also affirmed the Rule 32 court’s ruling on the brain-dysfunction
    claim, finding that Bell employed a “well thought-out defense strategy,” and
    determining that Bell had no cause to investigate Samra’s organic brain function
    any further than he did. As for the evidence provided by Dr. Gelbort and Dr.
    Mountz, the ACCA concluded that it was not compelling and that, in any event,
    23
    Case: 14-14869       Date Filed: 09/08/2015      Page: 24 of 42
    this additional evidence would not have “influenced the jury’s appraisal of Samra’s
    moral culpability.”      After quoting the trial court’s discussions of whether the
    evidence was more aggravating than mitigating and whether Bell was ineffective
    for not objecting to the gang writings, the ACCA adopted and affirmed those
    conclusions without discussion. Following the ACCA’s affirmance of the denial
    of Samra’s Rule 32 petition, the Alabama Supreme Court denied certiorari on
    September 19, 2008. See Ex parte Samra, 
    34 So. 3d 737
    , 737 (Ala. 2008) (table
    decision).8
    E. Federal Habeas Proceedings
    Samra filed a petition for habeas corpus under 28 U.S.C. § 2254 in the
    Northern District of Alabama on October 26, 2007, and an amended petition on
    February 21, 2014. See Samra § 2254 Proceeding, 
    2014 WL 4452676
    , at *10.
    The district court denied Samra’s § 2254 petition on September 5, 2014. 
    Id. at *46.
    Applying the doubly deferential standard of Strickland v. Washington, 
    466 U.S. 668
    , 
    104 S. Ct. 2052
    (1984), and § 2254 to Samra’s ineffective-assistance-of-
    counsel claims, the district court determined that the ACCA did not misapply
    Strickland when it held that Bell’s investigation of Samra’s brain condition was not
    8
    After Duke’s death sentence was vacated in light of the United States Supreme Court’s
    decision in Roper v. Simmons, 
    543 U.S. 551
    , 
    125 S. Ct. 1183
    (2005), because Duke was under
    eighteen at the time of the murders, Samra filed a successive Rule 32 petition arguing that his
    death sentence should be set aside because, essentially, it was unjust and disproportionate to
    execute Samra, who, although nineteen years old at the time of the offense, was a less culpable
    party than Duke. The state courts rejected this argument. The issues raised in Samra’s
    successive Rule 32 petition are not before us.
    24
    Case: 14-14869     Date Filed: 09/08/2015   Page: 25 of 42
    deficient. 
    Id. at *27.
    The district court noted that Bell had obtained Dr. Scott’s
    evaluation and an MRI, and he had investigated Samra’s background (including his
    tremors) and interacted with Samra. 
    Id. Because nothing
    uncovered by Bell would
    have raised “red flags” as to an organic brain dysfunction, the district court deemed
    Bell’s investigation to be extensive and not deficient. 
    Id. at *28-29.
    The district court also distinguished Samra’s reliance on the Fifth Circuit
    case of Lockett v. Anderson, 
    230 F.3d 695
    (5th Cir. 2000). After observing that
    was it not a Supreme Court precedent, the district court concluded that “Samra has
    not presented any evidence that he has a mental illness or any connection between
    his purported ‘organic brain damage’ and his participation in these murders.” 
    Id. at *29.
    Nor did the district court find that the prejudice determination was contrary to
    law. As the district court viewed the record, the murders were heinous, the SPECT
    test was not trustworthy, and all of the Rule 32 testing was merely cumulative of
    the evidence of Samra’s low IQ. 
    Id. at *30-31.
    The district court similarly found Bell’s decision to emphasize Samra’s
    membership in the FOLKS gang as unassailable because Bell reached that decision
    after concluding that Samra had no mental defect or illness that would serve as a
    defense. 
    Id. at *34.
    With regard to Bell’s presentation of Dr. Ronan’s testimony,
    the district court saw no error because her overall conclusion supported Bell’s
    defense theory, even if her testimony about the lack of gang involvement did not.
    25
    Case: 14-14869    Date Filed: 09/08/2015    Page: 26 of 42
    
    Id. at *35.
    The district court likewise determined that Bell’s failure to object to the
    photographic gang-related evidence was in keeping with his defense strategy, so
    the state court did not misapply Strickland when it rejected Samra’s argument. 
    Id. at *37.
    The district court did not discuss the prejudice prong of Strickland with
    respect to the gang-related claims. See 
    id. at *31-37.
    Turning to Samra’s ineffective-assistance-of-appellate-counsel claim, the
    district court concluded that the ACCA “mischaracterized” the claim as a defective
    indictment issue rather than a notice issue. See 
    id. at *38.
    And because the state
    courts did not address the merits of the notice claim, the district court determined
    that de novo review was appropriate rather than deferential review under § 2254.
    
    Id. at *39.
    Even applying de novo review, though, the district court determined that
    Samra’s claim failed. 
    Id. at *39-40.
    The district court held that due process
    requires that a defendant receive notice of the charges against him only, not notice
    of the statutory aggravating factors that the state intended to use to justify a death
    sentence. 
    Id. at *40.
    Because no due-process right existed, the district court
    reasoned, Bell was not deficient for failing to raise the argument on appeal. 
    Id. Having concluded
    that Bell’s performance was not deficient, the court did not
    further address the prejudice prong of this inquiry. See 
    id. 26 Case:
    14-14869      Date Filed: 09/08/2015        Page: 27 of 42
    Following the district court’s rejection of his federal habeas petition, Samra
    sought appellate review. We granted a certificate of appealability with respect to
    two issues:
    (1) Did the Alabama courts unreasonably apply
    Strickland v. Washington, 
    466 U.S. 668
    , 
    104 S. Ct. 2052
                   (1984), when they determined that Samra’s trial counsel
    was not ineffective when trial counsel (a) failed to
    investigate and present evidence of brain impairment in
    mitigation of the death penalty; (b) introduced evidence
    during trial of Samra’s affiliation with a Satanic gang;
    and (c) did not object to the introduction at trial of
    Satanic markings found in his co-defendant’s bedroom
    and Samra’s own gang tattoos.
    (2) As to the claim that appellate counsel rendered
    ineffective assistance by failing to raise the issue of
    whether due process requires pretrial notice to a capital
    defendant of the specific statutory aggravating
    circumstances that the State intends to rely on in seeking
    a death sentence: (a) Is any component of this claim
    barred by the Teague 9 non-retroactivity doctrine? (b) Is
    28 U.S.C. § 2254(d) deference due on any component of
    this claim? (c) Does due process require pre-trial notice
    to a capital defendant of which specific statutory
    aggravating circumstances the State intends to rely on in
    seeking a death sentence? (d) Was it ineffective
    assistance for the petitioner’s appellate counsel not to
    raise this issue on direct appeal?
    9
    Teague v. Lane, 
    489 U.S. 288

    II.
    A. General Habeas Standards
    Federal law permits a prisoner held “in custody pursuant to the judgment of
    a State court” to seek habeas relief “only on the ground that he is in custody in
    violation of the Constitution or laws or treaties of the United States.” 28 U.S.C. §
    2254(a). Generally, a prisoner must first “fairly present” his federal claims to the
    state court and exhaust his state-court remedies before seeking federal habeas
    relief. Snowden v. Singletary, 
    135 F.3d 732
    , 735 (11th Cir. 1998).
    We review a district court’s denial of a § 2254 petition de novo. Sims v.
    Singletary, 
    155 F.3d 1297
    , 1304 (11th Cir. 1998). If the state courts do not address
    the merits of a fairly presented claim, a federal court’s review of that claim is de
    novo. See Davis v. Sec’y for the Dep’t of Corr., 
    341 F.3d 1310
    , 1313 (11th Cir.
    2003) (per curiam). But when a state court has adjudicated a prisoner’s claim on
    the merits, a federal court may not grant habeas relief with respect to such a claim
    unless the state court’s adjudication
    (1) resulted in a decision that was contrary to, or involved
    an unreasonable application of, clearly established
    Federal law, as determined by the Supreme Court of the
    United States; or
    (2) resulted in a decision that was based on an
    unreasonable determination of the facts in light of the
    evidence presented in the State court proceeding.
    28 U.S.C. § 2254(d).
    28
    Case: 14-14869     Date Filed: 09/08/2015    Page: 29 of 42
    These standards are highly deferential and demand that we give state-court
    decisions the benefit of the doubt. Evans v. Sec’y, Dep’t of Corr., 
    703 F.3d 1316
    ,
    1325 (11th Cir. 2013) (en banc). A decision “is not ‘contrary to’ federal law unless
    it ‘contradicts the United States Supreme Court on a settled question of law or
    holds differently than did that Court on a set of materially indistinguishable facts.’”
    
    Id. (quoting Cummings
    v. Sec’y for Dep’t of Corr., 
    588 F.3d 1331
    , 1355 (11th Cir.
    2009)). Nor is a state court’s decision “an ‘unreasonable application’ of federal
    law unless the state court ‘identifies the correct governing legal principle as
    articulated by the United States Supreme Court, but unreasonably applies that
    principle to the facts of the petitioner’s case, unreasonably extends the principle to
    a new context where it should not apply, or unreasonably refuses to extend it to a
    new context where it should apply.’” 
    Id. The federal
    court does not ask whether
    the state decision is correct, but rather whether it is unreasonable. 
    Id. B. Ineffective
    Assistance of Counsel
    To prevail under Strickland on a claim of ineffective assistance of trial
    counsel, a petitioner must show that (1) counsel’s performance was so deficient
    that “counsel was not functioning as the ‘counsel’ guaranteed” by the Sixth
    Amendment and (2) that counsel’s performance prejudiced the defense to the
    extent that the defendant was deprived of a fair, reliable trial. 
    Strickland, 466 U.S. at 687
    , 104 S. Ct. at 2064. A court need not conduct this analysis in a particular
    29
    Case: 14-14869    Date Filed: 09/08/2015           Page: 30 of 42
    sequence, and a court need not address both prongs if a petitioner fails to make a
    required showing on one of them. 
    Id. at 697,
    104 S. Ct. at 2069.
    Establishing deficient performance requires the petitioner to demonstrate
    that   “‘counsel’s   representation    fell        below   an     objective      standard   of
    reasonableness.’” Harrington v. Richter, 
    562 U.S. 86
    , 104, 
    131 S. Ct. 770
    , 787
    (2011) (quoting 
    Strickland, 466 U.S. at 688
    , 104 S. Ct. at 2064). A court applies a
    strong presumption that counsel’s representation fell within the wide range of
    reasonable professional conduct.      
    Id. To show
    prejudice, a petitioner “must
    demonstrate ‘a reasonable probability that, but for counsel’s unprofessional errors,
    the result of the proceeding would have been different. A reasonable probability is
    a probability sufficient to undermine confidence in the outcome.’” 
    Id. (quoting Strickland,
    466 U.S. at

    ). We evaluate claims of ineffective
    assistance of appellate counsel under the same Strickland standards. Philmore v.

    Samra contends that he is entitled to federal habeas relief because his trial
    counsel was ineffective. Specifically relevant to this appeal, he asserts that his
    counsel failed to adequately investigate and present evidence of brain dysfunction
    in mitigation of the death penalty.         He also contends that Bell’s strategy of
    emphasizing Samra’s involvement in a satanic gang, including Bell’s failure to
    30
    Case: 14-14869    Date Filed: 09/08/2015   Page: 31 of 42
    object to evidence of certain gang-related drawings and tattoos was more
    aggravating than mitigating. For the reasons discussed in this section, we find that
    Samra has failed to establish prejudice with respect to his ineffective-trial-counsel
    claim. And because he has not shown prejudice, we neither reach nor offer any
    opinion on trial counsel’s performance. See Strickland, 466 U.S. at 
    697, 104 S. Ct. at 2069
    .
    A. Bell’s Investigation of Samra’s Brain Function
    Samra argues that the ACCA unreasonably applied federal law when it
    determined (a) that Bell’s investigation of Samra’s neuropsychological health was
    not deficient and (b) that the failure to introduce the evidence developed by Dr.
    Gelbort and Dr. Mountz during the Rule 32 proceedings did not prejudice Samra.
    With respect to the deficient-performance prong of the Strickland analysis, Samra
    contends that Bell was deficient for not pursuing functional brain testing,
    particularly a SPECT test, and also for not pursuing further neuropsychological
    testing when Bell’s own expert, Dr. Scott, had recommended those tests. Samra
    asserts that the failure to investigate prejudiced him because the postconviction
    evidence establishes that Samra does suffer from organic brain dysfunction and
    that such evidence is powerfully mitigating, thus undermining confidence in the
    death sentence.
    31
    Case: 14-14869     Date Filed: 09/08/2015   Page: 32 of 42
    The state counters that Bell’s investigation of Samra’s brain function was
    adequate. In the state’s view, moreover, Samra was not prejudiced because the
    new evidence is cumulative and consistent with the evidence presented of Samra’s
    borderline intellectual ability, does not undermine Samra’s culpability, and would
    have had no chance of altering the jury’s balance of aggravating and mitigating
    factors in light of the brutal nature of the killings. We agree with the state that
    Samra has failed to establish that the state courts unreasonably applied Strickland
    when they found no prejudice.
    As we have noted, to demonstrate prejudice under Strickland, Samra must
    “show that there is a reasonable probability that, but for counsel’s unprofessional
    errors, the result of the proceeding would have been different.” 
    Strickland, 466 U.S. at 694
    , 104 S. Ct. at 2068. “In assessing prejudice, we reweigh the evidence
    in aggravation against the totality of available mitigating evidence,” including all
    mitigating evidence produced at trial and developed during the collateral
    proceedings. Wiggins v. Smith, 
    539 U.S. 510
    , 534, 
    123 S. Ct. 2527
    , 2542 (2003);
    Williams v. Taylor, 
    529 U.S. 362
    , 397-98, 
    120 S. Ct. 1495
    , 1515 (2000).
    As described above, Dr. Gelbort’s examination, which was largely
    consistent with Dr. King’s examination, suggested some mild impairment of
    Samra’s brain’s functioning.     But Dr. Mountz’s SPECT scan indicated just a
    different blood flow in one region of Samra’s brain approximately one standard
    32
    Case: 14-14869     Date Filed: 09/08/2015   Page: 33 of 42
    deviation below the “normal” level of flow. And while Samra emphasizes what he
    describes as the abnormal nature of this blood flow, Dr. Mayberg opined that this
    result still fell within “normal” levels. Nor does Samra present any argument or
    evidence that his blood-flow level has had any cognitive or behavioral impact. In
    other words, there is no evidence that the blood flow level was so much an organic
    brain problem, as opposed to merely an organic brain anomaly, to the extent that it
    was even anomalous. Even Dr. Mountz testified, carefully, that the abnormal
    blood flow was “not inconsistent” with Dr. Gelbort’s diagnosis of mild
    impairment, not that the blood flow itself was indicative of impairment. And Dr.
    Mountz added that further analysis would be required to determine what the
    section of Samra’s brain with the different blood flow actually controls. While we
    recognize, of course, that any abnormality is admissible mitigation evidence, even
    assuming that the blood flow was abnormal, in the absence of any evidence
    explaining its effect on Samra, its mitigating impact is significantly reduced.
    Samra cites a number of cases that stand for the proposition that organic
    brain damage can be a significant mitigating factor in capital sentencing
    proceedings. And we agree and have recognized in the past that evidence of
    organic brain damage can be a powerful mitigating factor. See, e.g., Debruce v.
    Comm’r, Ala. Dep’t of Corr., 
    758 F.3d 1263
    , 1276 (11th Cir. 2014); Ferrell v.
    Hall, 
    640 F.3d 1199
    , 1234-35 & n.17 (11th Cir. 2011). But in those cases, the
    33
    Case: 14-14869     Date Filed: 09/08/2015   Page: 34 of 42
    evidence established the existence of impairment—indeed, significant brain
    impairment. See 
    Debruce, 758 F.3d at 1270
    (petitioner suffered from “lingering
    emotional damage and social impairments associated with having been raised in a
    violent community,” as well as “blackout episodes consistent with seizures
    accompanied by periods of non-responsive staring and loss of memory”); 
    Ferrell, 640 F.3d at 1203
    , 1234 (petitioner suffered from “extensive” and “disabling . . .
    organic brain damage to the frontal lobe, bipolar disorder, and temporal lobe
    epilepsy”). Even Lockett, the Fifth Circuit case upon which Samra heavily relies,
    dealt with a defendant who likely suffered from temporal-lobe epilepsy and
    paranoid 
    schizophrenia. 230 F.3d at 713-14
    . Unlike the cases he cites, Samra
    possesses mild functional impairments and, based on his MRI scan, suffers from
    no structural brain abnormalities.
    Contrary to Samra’s argument on appeal that his counsel presented a paucity
    of mitigating evidence at his trial, the sentencing jury heard, and the sentencing
    judge found, several mitigating factors related to Samra’s mental health, including
    his borderline intelligence, schooling problems, substance abuse, childhood hand
    tremors, and lack of emotionality. And unlike in cases such as Wiggins, Debruce,
    or Ferrell, there is absolutely no evidence in Samra’s case of an abusive
    upbringing that could have contributed to a mental disorder.
    34
    Case: 14-14869     Date Filed: 09/08/2015   Page: 35 of 42
    Ultimately, after weighing the evidence adduced in the postconviction
    proceedings from Dr. Gelbort and Dr. Mountz along with the evidence introduced
    during the guilt and sentencing phases, the state court concluded that Samra had
    not established a reasonable probability that this mitigating evidence undermines
    confidence in his unanimous death sentence.         This was not an unreasonable
    application of Strickland’s prejudice analysis. 
    Harrington, 562 U.S. at 100-01
    ,
    131 S. Ct. at 785.
    The fact remains that Samra participated in the gruesome murders of four
    people—including personally slitting the throat of a seven-year-old girl, causing
    her to drown in her own blood—all because his friend Duke’s father refused to let
    Duke use a pickup truck. Samra § 2254 Proceeding, 
    2014 WL 4452676
    , at *1.
    None of the brain-impairment evidence Samra has provided leads us to conclude
    that a jury would have found that the killings were less heinous, atrocious, or cruel,
    or that Samra’s mild brain impairments outweighed the heinousness, atrociousness,
    or cruelty of the crime, had evidence similar to that presented at the Rule 32
    hearing been introduced during the penalty phase of Samra’s trial. Absent the
    required showing of prejudice, we do not consider the sufficiency of Bell’s
    investigation. Samra’s claim that his trial counsel was ineffective for failing to
    adequately investigate Samra’s brain function must be denied.
    35
    Case: 14-14869    Date Filed: 09/08/2015   Page: 36 of 42
    B. Bell’s Gang-Influence Strategy
    Samra contends that Bell’s strategy of emphasizing Samra’s membership in
    the FOLKS gang—including its connection to Satan, its violent character
    (including alleged matricide), and its association with drugs and prison—put
    evidence that was more aggravating than mitigating in front of the jury.          In
    Samra’s view, Bell was deficient for choosing and presenting this strategy and for
    failing to object to the prosecution’s introduction of other photographic evidence of
    FOLKS-related markings found in Duke’s room and Samra’s tattoos. For its part,
    the state contends that Bell’s strategic decision to present a “substantial
    domination” defense is unassailable.
    While neither the state courts nor the district court reached the prejudice
    prong of this analysis, we find under a de novo review that, regardless of the
    competency of Bell’s chosen strategy, Samra has failed to establish a reasonable
    probability that it undermines confidence in the death sentence. We acknowledge,
    as we have previously, that evidence of gang membership and satanic worship has
    the potential to unduly prejudice a defendant. See United States v. Jernigan, 
    341 F.3d 1273
    , 1284-85 (11th Cir. 2003) (“[W]e do not wish to understate the
    prejudicial effect that evidence of a criminal defendant’s gang membership may
    entail. Indeed, modern American street gangs are popularly associated with a
    wealth of criminal behavior and social ills, and an individual’s membership in such
    36
    Case: 14-14869      Date Filed: 09/08/2015       Page: 37 of 42
    an organization is likely to provoke strong antipathy in a jury.”); cf. McCorkle v.
    Johnson, 
    881 F.2d 993
    , 995 (11th Cir. 1989) (per curiam) (recognizing the
    “violence inherent in Satan worship”).
    But the facts of this crime belie this prejudice here. Even if we disregard the
    gang-related evidence and argument, the state presented overwhelming evidence—
    including Samra’s own confession—of the heinousness of this crime. By Samra’s
    own admission, after he assisted in killing three people, he slit the throat of a
    seven-year-old girl who was pleading and struggling for her life. Samra § 2254
    Proceeding, 
    2014 WL 4452676
    , at *1. We find no reasonable probability that,
    absent evidence or discussion of Samra’s gang involvement, the jury would not
    have found these murders to be as especially heinous, atrocious, or cruel as it
    found them. 
    Harrington, 562 U.S. at 104
    , 131 S. Ct. at 787. As a result, Samra’s
    claim that his trial counsel was ineffective for pursing a gang-related strategy and
    for failing to object to gang-related evidence must be denied.10
    IV.
    Samra also contends that he is entitled to federal habeas relief because his
    appellate counsel was constitutionally ineffective. Specifically, Samra argues that
    he had a due-process right to be informed before his trial of the actual aggravating
    10
    As with the brain-dysfunction claim, we do not opine on whether counsel’s selection
    and implementation of this defense strategy was constitutionally sufficient. See Strickland, 466
    U.S. at 
    697, 104 S. Ct. at 2069
    .
    37
    Case: 14-14869       Date Filed: 09/08/2015       Page: 38 of 42
    factor or factors upon which the state intended to rely in seeking the death penalty
    and that his appellate counsel was deficient for not challenging the trial court’s
    rejection of this argument. Without deciding whether such a due-process right
    exists, we find that Samra’s counsel was not deficient in failing to raise the issue
    during Samra’s direct appeals. 11
    Samra bases his due-process notice argument on two Supreme Court cases
    that were decided before his conviction became final: Jones v. United States, 
    526 U.S. 227
    , 
    119 S. Ct. 1215
    (1999) and Apprendi v. New Jersey, 
    530 U.S. 466
    , 
    120 S. Ct. 2348
    (2000). In Jones, the Supreme Court construed the federal carjacking
    statute, 18 U.S.C. § 2119, and concluded that the statutory provisions that
    enhanced a sentence based on a finding of bodily injury or death should not be
    viewed merely as sentencing factors but as elements of distinct offenses that must
    be charged in an indictment.           
    See 526 U.S. at 251-52
    , 119 S. Ct. at 1228.
    Similarly, in Apprendi, the Court confirmed the principle expressed in Jones:
    “Other than the fact of a prior conviction, any fact that increases the penalty for a
    crime beyond the prescribed statutory maximum must be submitted to a jury, and
    proved beyond a reasonable doubt.” 
    Apprendi, 530 U.S. at 490
    , 120 S. Ct. at
    2362-63. Under Apprendi, sentencing factors that increase punishment beyond the
    11
    The state contends that the district court erred in considering this claim de novo after
    determining that the Alabama state courts had mischaracterized Samra’s claim. Instead, the state
    urges that we extend double deference under § 2254 and Strickland to the manner in which the
    state courts did decide this claim. We need not resolve this issue, however, because even under
    de novo review, Samra has failed to demonstrate deficient performance.
    38
    Case: 14-14869    Date Filed: 09/08/2015       Page: 39 of 42
    statutory maximum are “the functional equivalent of an element of a greater
    offense than the one covered by the jury’s guilty verdict.” 
    Id. at 494
    n.19, 120 S.
    Ct. at 2365 n.19 (emphasis added).
    Because the statutory aggravating factors are required under Alabama law to
    increase the maximum punishment from life imprisonment to death, in Samra’s
    view, they constitute elements of the capital offense. And because due process
    generally requires advance notice of offense elements, Samra argues that he had a
    constitutional entitlement to advance notice of the specific aggravating factors that
    the state was pursuing in his case. Samra asserts that the performance of his
    appellate counsel was constitutionally deficient because counsel neglected to
    challenge the trial court’s refusal to provide this notice.
    But   Samra   cannot    demonstrate    that   his     appellate   counsel   was
    constitutionally deficient for failing to raise this due-process argument. We judge
    counsel’s performance from the perspective of an attorney operating at the time
    that the challenged decision was made. 
    Strickland, 466 U.S. at 689
    , 104 S. Ct. at
    2065. Here, Samra has cited no precedent—and we have found none—existing at
    the time of his direct appeal that required a state to provide advance notice of the
    specific aggravating factor it intended to prove.             In fact, in our view, the
    circumstances existing at that time actually counseled that such an argument lacked
    merit.
    39
    Case: 14-14869    Date Filed: 09/08/2015   Page: 40 of 42
    First, the Supreme Court had granted certiorari in Jones just a month before
    Samra filed his notice of direct appeal, and it did not decide Apprendi until after
    the Alabama Supreme Court upheld Samra’s death sentence. See Jones v. United
    States, 
    523 U.S. 1058
    , 
    118 S. Ct. 1405
    (1998) (Mem.) (amending the grant of
    certiorari to two specific questions); 
    Apprendi, 530 U.S. at 466
    , 120 S. Ct. at 2348;
    Ex parte 
    Samra, 771 So. 2d at 1122
    . Samra suggests that his appellate counsel
    should have recognized from the grant of certiorari in Jones—a case involving the
    federal carjacking statute—that the issue of whether a state is required to provide
    capital defendants with advance notice of specific aggravating factors was an
    unresolved question of law. Although an exceptionally skilled or creative attorney
    may have anticipated the arguments and outcome of Jones (and later Apprendi)
    and sought to extend that rationale to the capital-sentencing context, we have
    repeatedly held that an attorney is not required to foresee changes in the law to
    provide constitutionally sufficient representation. See, e.g., LeCroy v. Sec’y, Fla.
    Dep’t of Corr., 
    421 F.3d 1237
    , 1261 n.27 (11th Cir. 2005) (“[A]ppellate counsel
    was not ineffective for failing to anticipate the change in the law”); Spaziano v.
    Singletary, 
    36 F.3d 1028
    , 1039 (11th Cir. 1994) (“We have held many times that
    ‘[r]easonably effective representation cannot and does not include a requirement to
    make arguments based on predictions of how the law may develop.’” (quoting
    40
    Case: 14-14869    Date Filed: 09/08/2015    Page: 41 of 42
    Elledge v. Dugger, 
    823 F.2d 1439
    , 1443 (11th Cir.) (per curiam), modified in
    unrelated part, 
    833 F.2d 250
    , 250 (11th Cir. 1987) (per curiam)).
    Second, a substantial body of federal and state case law available to his
    appellate counsel at the time, while not necessarily foreclosing Samra’s due-
    process argument, strongly suggested such an argument would face an uphill battle
    with little chance of success. See, e.g., Walton v. Arizona, 
    497 U.S. 639
    , 647-49,
    
    110 S. Ct. 3047
    , 3054-55 (1990) (expressly holding that capital aggravating factors
    are not elements of the offense, a holding that was specifically affirmed in Jones
    and Apprendi and not overruled until Ring), overruled by 
    Ring, 536 U.S. at 589
    ,
    122 S. Ct. at 2432; Spenkelink v. Wainwright, 
    442 U.S. 1301
    , 1303-06, 
    99 S. Ct. 2091
    , 2092-94 (Rehnquist, Circuit Justice 1979) (denying stay of execution and
    asserting belief that no four Justices would agree to hear a claim that due process
    required advance notice of capital aggravating factors); Clark v. Dugger, 
    834 F.2d 1561
    , 1566 (11th Cir. 1987) (due process satisfied by statute listing potential
    aggravating factors and particularized notice of specific factors is not required);
    Knotts v. State, 
    686 So. 2d 431
    , 448-449 (Ala. Crim. App. 1995) (“A defendant has
    no right to advance notice of the state's intention to rely on any of the aggravating
    circumstances enumerated in § 13A–5–49.”).
    In light of this case law existing at the time that Samra’s appeal was filed, an
    attorney could not be faulted for declining to pursue the argument that capital
    41
    Case: 14-14869    Date Filed: 09/08/2015   Page: 42 of 42
    sentencing factors were functionally equivalent to the elements of an offense and
    were required by due process to be disclosed in advance of trial. 
    Philmore, 575 F.3d at 1264
    (“In assessing an appellate attorney’s performance, we are mindful
    that ‘the Sixth Amendment does not require appellate advocates to raise every non-
    frivolous issue.’ Rather, an effective attorney will weed out weaker arguments,
    even though they may have merit.” (citation omitted) (quoting Heath v. Jones, 
    941 F.2d 1126
    , 1130-31 (11th Cir. 1991)). Thus, even if counsel had foreseen such an
    argument—and he was not required to have done so—counsel would not have
    been deficient in declining to pursue that argument. Because Samra’s appellate
    counsel’s performance was not deficient, Samra cannot prevail on his ineffective-
    appellate-counsel claim here. We therefore do not address the prejudice prong and
    the underlying merits of Samra’s due-process argument. See Strickland, 466 U.S.
    at 
    697, 104 S. Ct. at 2069
    ; 
    Philmore, 575 F.3d at 1264
    -65.
    V.
    For the reasons set forth above, we find that Samra has failed to make the
    required showings to prevail on his ineffective-assistance-of-counsel claims.
    Accordingly, we affirm the district court’s denial of Samra’s § 2254 petition.
    AFFIRMED.
