    BOUDIN, Circuit Judge.        Eric Brown, now in state prison
    serving two life terms for first degree murder, was denied habeas
    corpus relief in the federal district court, Brown v. O'Brien, 
    755 F. Supp. 2d 335
    (D. Mass. 2010), and now appeals. The factual
    background,   recounted   in   detail   in   the   state   court   decision
    upholding his convictions, Commonwealth v. Brown, 
    872 N.E.2d 711
    (Mass. 2007), is readily summarized.
    In the early morning of June 16, 1996, two men were shot
    at close range with a shotgun in Boston's South End and both were
    killed.   The day before the murders, Brown had accompanied his
    friend Dwight Bobbitt, a security guard who had the credentials to
    obtain firearms, to a Boston sporting goods store.            After Brown
    supplied Bobbitt with money, Bobbitt purchased a shotgun selected
    by Brown, together with shells, and turned both the weapon and the
    ammunition over to Brown.      
    Brown, 872 N.E.2d at 716-17
    .        Bobbitt
    thereafter reported the shotgun as stolen, but later admitted he
    had purchased it for Brown.     
    Id. at 716
    n.15.
    Then, sometime after midnight on June 16, 1996, Brown in
    the company of several friends (including Bobbitt) fired the
    shotgun into the air several times outside of his house in Roxbury.
    Brown was back inside the house when police arrived to investigate,
    and after they left he returned outside wearing a thigh-length
    green jacket and black boots.       Brown again fired into the air
    -2-
    several times and then left on foot toward Boston's South End
    carrying the shotgun with him.     
    Brown, 872 N.E.2d at 716-17
    .
    Witnesses in the South End testified that in the early
    morning hours on Appleton Street, a number of people were outside
    socializing and walking about.   At about 3:30 in the morning, a man
    approached one of these people, Athos Oliveira, and shot him twice
    with a shotgun, the second shot hitting Oliveira in the face and
    killing him.    The assailant continued down the street, encountered
    one Thomas Meyer, killed him with a shot to the back of the head,
    and left the scene.    
    Brown, 872 N.E.2d at 717
    .
    Five witnesses who either heard or saw one or the other
    of the two crimes--and who eventually testified at Brown's trial--
    could not identify Brown as the man who killed Oliveira and Meyer.
    But most of the witnesses identified the assailant as a black male
    and one identified the assailant as having "short African-American
    hair"; another said he was wearing a green, three-quarter length
    jacket; two said that he was about 5'8'' or so (Brown was in fact
    5'7''); and one said he was 160 pounds (Brown was 150 pounds).
    Although one said the jacket was waist-length, three agreed it was
    thigh-length.
    Ten days after the crimes, on June 26, 1996, a policeman
    stopped Brown for erratic driving in a community not very far from
    Boston and eventually discovered a shotgun and a spent shell on the
    floor of the van he was driving.    
    Brown, 872 N.E.2d at 718
    .   Shell
    -3-
    casings recovered at the scenes where Oliveira and Meyer died were
    matched   to   the   shotgun   recovered    from   Brown's    van;   Bobbitt
    confirmed that this was the weapon he had bought and also that a
    green jacket that police found in Brown's apartment matched the
    color of the one Brown had worn on the night of the shootings.
    Brown was indicted in August 1996 but was not put on
    trial until March 2001.        In the interim, Brown was committed to
    Massachusetts' Bridgewater State Hospital ("Bridgewater") for an
    extended period to determine his competence to stand trial.
    Successive conflicting determinations as to competency followed
    along with re-commitments for more observation.1             Finally, after
    hearings in January and March 2001, he was twice determined to be
    competent to stand trial by the state judge, although defense
    experts and a court clinician disagreed. A trial commenced in late
    March 2001 and lasted for four weeks.
    At trial, the principal defense witness (Dr. Rosmarin),
    a   forensic   psychiatrist    from    Massachusetts   General    Hospital,
    testified that Brown was a paranoid schizophrenic who exhibited
    prominent symptoms of the disease and suffered from delusions of
    persecution, a horror of homosexuality, and voices telling him to
    1
    Brown was initially found competent to stand trial in
    February 1997 but was then re-committed to Bridgewater at its
    request for further observation and treatment.       After further
    hearings and evaluations, he was held incompetent to stand trial in
    April 1998 and re-committed to Bridgewater. Brown was then held
    competent in December 1998 but then re-committed for further
    observation.

    kill those he believed to be "sexual immoralizers."        He also gave
    his opinion that at the time of the deaths, Brown was not sane and
    lacked   criminal   responsibility     under   the   standard   used   in
    Massachusetts.2
    Two treating psychiatrists and a treating psychologist
    from Bridgewater agreed that Brown was a paranoid schizophrenic
    suffering from delusions, and described the symptoms they had
    observed during his time at Bridgewater.       Supporting evidence from
    friends and family members confirmed Brown's mental and emotional
    deterioration in 1995 and 1996.        But several witnesses for the
    prosecution testified on rebuttal that Brown seemed normal to them
    both before and after the killings and the prosecution's expert
    testified, albeit rather summarily and after limited exposure to
    him, that Brown was not psychotic on the day of the shootings.
    The jury convicted Brown in 2001 of two separate counts
    of first degree murder, as well as other less serious firearms-
    related offenses, and on each murder count he received a life
    sentence.    The Supreme Judicial Court of Massachusetts ("SJC")

    Commonwealth v. DiPadova, 
    951 N.E.2d 891
    , 897 (Mass. 2011)
    ("Under the McHoul test, a defendant is not criminally responsible
    for his actions—and, therefore entitled to a verdict of not
    guilty—if, at the relevant time and due to a mental illness (mental
    disease or defect), he lacks the substantial capacity to appreciate
    the wrongfulness of an action or to act in conformity with the
    law." (citing Commonwealth v. McHoul, 
    226 N.E.2d 556
    (Mass.
    1967))).
    -5-
    affirmed the conviction.        Brown, 
    872 N.E.2d 711
    .      Brown then filed
    a habeas petition in the federal district court, 28 U.S.C. § 2254
    (2006).       The magistrate judge recommended that the habeas petition
    be dismissed on the merits, and the district judge agreed, but also
    granted a certificate of appealability as to four different issues,
    which are now before us.        
    Brown, 755 F. Supp. 2d at 337
    .
    A federal court may grant a writ of habeas corpus when a
    state court adjudication 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   "resulted   in   a   decision   that   was   based   on   an
    unreasonable determination of the facts."            28 U.S.C. § 2254(d)(1)-
    (2).3       There are additional provisions relating to factual issues,
    
    id. § 2254(e)(1),
    but any ambiguity resulting from the interaction
    of the factual provisions, see          Wood v. Allen, 
    130 S. Ct. 841
    , 848-
    49 (2010) (noting circuit split), does not impact the outcome here.
    Sufficiency of the evidence.        Brown's first argument is
    that under Jackson v. Virginia, 
    443 U.S. 307
    (1979), no reasonable
    jury could find that he is the person who committed the murders.
    3
    Under the "law" prong, a state court's decision is "contrary
    to" federal law either if it "arrives at a conclusion opposite to
    that reached by [the Supreme] Court on a question of law or if the
    state court decides a case differently than [the Supreme] Court has
    on a set of materially indistinguishable facts."       Williams v.
    Taylor, 
    529 U.S. 362
    , 413 (2000). Review under the "fact" prong is
    limited to "the record that was before [the] state court." Cullen
    v. Pinholster, 
    131 S. Ct. 1388
    , 1400 (2011).
    -6-
    The SJC rejected this claim on the merits, 
    Brown, 872 N.E.2d at 723-24
    , so our review is deferential.             But, in this instance,
    deference to the state court is beside the point: if an identical
    insufficiency of evidence claim were made on direct appeal after a
    federal trial, the evidence would be entirely sufficient to support
    a jury verdict finding that Brown shot the two victims.
    Brown    says    the     prosecution   established,     at   most,
    "circumstantial evidence" connecting Brown and the gun used in the
    shootings.     The prosecution's case was "circumstantial" in the
    limited sense that no one at the scene testified in court to
    recognizing Brown as the shooter; but there was direct eyewitness
    evidence (1) that the man was similar to Brown in race, height,
    weight, hair style and green jacket; (2) that Brown left for the
    South End with his shotgun an hour or two before the murders; (3)
    that he possessed that shotgun less than two weeks later; and (4)
    that the shell casings at the scene matched his weapon.
    True, the credibility of Bobbitt (who testified to the
    purchase of the gun and the incident in front of Brown's house
    before the murders) was open to attack, although his version of the
    gun purchase was not effectively challenged.                The eyewitness
    testimony as to identity of the shooter was in some respects vague;
    and certainly the jury could have doubted Brown's sanity. But this
    last   issue   is   not    before   us   and   Brown's   plainly   disturbed
    personality, if the disturbance fell short of insanity, provided an
    -7-
    explanation for what otherwise might be viewed as a senseless, and
    therefore improbable, crime.
    Brown's counsel at trial conceded to the jury in closing
    that Brown had done the shootings, and sensibly concentrated on
    persuading the jury that Brown was insane.    In his presentation of
    the case, defense counsel provided strong expert and lay testimony
    that Brown was insane which would likely have persuaded many
    juries--especially because the prosecution had a bare minimum of
    expert evidence on its side and appeared to rely heavily on the
    doubtful inference that Brown cannot have been insane because he
    was fairly organized and systematic.
    However, under the Massachusetts standard (see note 2,
    above), showing a severe mental illness is not conclusive; the jury
    must also decide whether the illness prevented the defendant from
    appreciating the wrongfulness of his actions or conforming his
    conduct to the requirements of the law.   Commonwealth v. DiPadova,
    
    951 N.E.2d 891
    , 897 (Mass. 2011).      The main defense expert said
    Brown met this standard; the prosecution expert said that Brown was
    not even psychotic on the day of the murders; and the SJC upheld
    the jury verdict.   
    Brown, 872 N.E.2d at 731
    .    The insanity issue
    was not pressed in the habeas proceeding.
    Instead, in this court, Brown presses his attack on the
    sufficiency of the identification evidence along two lines. First,
    counsel points out that under Massachusetts law, the evidence can
    -8-
    be found insufficient based solely on what is presented in the
    prosecutor's opening case (if the defendant files a motion at the
    close of the prosecution's case);4 and, on this premise, Brown's
    counsel urges that Jackson should be applied so as to disregard any
    evidence that came in only later through the defense case or
    prosecution rebuttal--where a limited amount of evidence adverse to
    Brown was admitted.
    But this Massachusetts practice is not imposed by federal
    constitutional law.    See LaMere v. Slaughter, 
    458 F.3d 878
    , 882
    (9th Cir. 2006); Hernandez v. Cowan, 
    200 F.3d 995
    , 998 (7th Cir.
    2000).    And Jackson does not say or even suggest that its test is
    to be applied to the prosecution's case but asks instead whether
    "after viewing the evidence in the light most favorable to the
    prosecution, any rational trier of fact could have found the
    essential elements of the crime beyond a reasonable 
    doubt." 443 U.S. at 318-19
    .     Accord McDaniel v. Brown, 
    130 S. Ct. 665
    , 672
    (2010).
    Second, Brown relies on O'Laughlin v. O'Brien, 
    568 F.3d 287
    (1st Cir. 2009), cert. denied, 
    130 S. Ct. 1142
    (2010), where
    4
    Mass. Crim. Pro. R. 25(a); see also Commonwealth v. Berry,
    
    727 N.E.2d 517
    , 522 (Mass. 2000). By contrast, under federal
    practice (and in the majority of states) a defendant can challenge
    the government's opening case after it is presented but, if the
    defendant then puts on his own case, any challenge to the
    sufficiency of the evidence must be based on the full record
    including anything presented in the defense case. See State v.
    Perkins, 
    856 A.2d 917
    , 932 n.23 (Conn. 2004) (listing federal and
    state practices).
    -9-
    this court on habeas review upheld a Jackson challenge.            In that
    case, the defendant was directly connected with a vicious assault
    only by some small blood stains in the defendant's apartment linked
    by DNA testing to him--not the victim--and his baseball bat--
    presumptively the murder weapon--found in the woods, also with
    blood stains which yielded no conclusive results after DNA testing.
    
    Id. at 294.
    In practice, Jackson challenges are rarely upheld on
    habeas and O'Laughlin is a rare exception.          The evidence showing
    that Brown committed the crime, described above, was far stronger
    than in O'Laughlin.       The only truly close issue as to guilt was
    Brown's sanity, and, as noted earlier, that issue was resolved
    against   Brown   based   on    what   can   charitably   be   regarded   as
    conflicting expert evidence, and anyway that issue is not before
    us.
    Intoxication.       Brown does raise a related state of mind
    issue on this appeal.      Specifically, Brown claims that the trial
    court should have granted his request for a jury instruction on
    intoxication. At trial, psychiatrists for both the defense and the
    prosecution made mention of Brown's drinking on the night of the
    crimes.   But, although Brown submitted a written request for an
    intoxication instruction, the trial judge's instructions to the
    jury did not include one on intoxication.        
    Brown, 872 N.E.2d at 728
    & n.39.
    -10-
    Massachusetts defines first degree murder as requiring
    premeditated malice, Mass. Gen. Laws ch. 265, § 1, and it endorses
    a jury instruction allowing the jury to consider intoxication to
    negate the required scienter; but such an instruction is required
    only       when    there      is   evidence     presented      of   intoxication      so
    debilitating it prevents the defendant from forming the requisite
    intent.       Commonwealth v. Morgan, 
    663 N.E.2d 247
    , 250-51 (Mass.
    1996).      On direct appeal, the SJC found there was no such evidence
    in this case.          
    Brown, 872 N.E.2d at 727-28
    .
    Brown's      principal      claim   here   is     that    the   "no    such
    evidence" ruling was an "unreasonable determination of the facts."
    28 U.S.C. § 2254(d)(2).             Ordinarily, errors of state law are not
    the basis for federal habeas relief, Estelle v. McGuire, 
    502 U.S. 62
    , 71-72 (1991); Pulley v. Harris, 
    465 U.S. 37
    , 41 (1984), but
    Brown also argues that the failure to give the instruction where
    the facts and law made it appropriate violated his due process
    rights.5      In all events, no evidence of disabling intoxication was
    presented         in   this    case--or    at   least    the    state    court      could
    permissibly so find.

    , 1243-45 (Mass.
    2006).
    -11-
    True, Brown points to testimony of the prosecution and
    defense psychiatric experts--Dr. Rogers and Dr. Rosmarin--both of
    whom       adverted    to   statements   Brown   himself    made    during   their
    examinations that he had drunk vodka and beer on the night of the
    murders; Dr. Rosmarin also mentioned some intake of marijuana; and
    Dr.    Rogers,    negating     insanity,    referred   to   Brown's    "drinking
    excessively" (and homophobia) to explain the killings.
    But Brown's statements to the doctors were admitted only
    to disclose the basis for their expert opinions on sanity and not
    for the truth of Brown's statements.             
    Brown, 872 N.E.2d at 728
    .
    The distinction was conveyed to Brown's jury and is not directly
    challenged in this case. Commonwealth v. Sama, 
    582 N.E.2d 498
    , 502
    (Mass. 1991), cited to us by Brown, did require an instruction but
    there the expert gave his own opinion that the defendant might have
    been hallucinating at the time of the crimes as a result of
    substance abuse.
    Thus,    strictly   speaking, practically       no    evidence   of
    Brown's drinking was properly before the jury.6                     Even if the
    statements were considered as substantive evidence, the SJC pointed
    out that
    6
    The prosecutor seems to have ignored the distinction in his
    closing by arguing that drinking and marijuana, rather than
    insanity, might have explained Brown's actions; but no objection
    was made by the defense; and the SJC held that "to the extent the
    argument was improper, it did not create a substantial likelihood
    of a miscarriage of justice." 
    Brown, 872 N.E.2d at 728
    n.41.
    -12-
    none of this evidence--or any other evidence
    admitted at trial--demonstrated how much or
    for how long Brown had been drinking on the
    night of the shootings or what effect any
    alcohol that he may have ingested had on him
    or whether his ability to form the requisite
    criminal intent was impaired.
    
    Brown, 872 N.E.2d at 728
    (internal citation omitted).    Assuming a
    federal issue exists, the state court's fact-based assessment
    rejecting such an instruction was not "unreasonable," given the
    lack of any specific testimony about a debilitating impact.   
    Wood, 130 S. Ct. at 849
    .
    Competence.   Brown's third argument on habeas is that he
    was not competent to stand trial, or at least that the procedures
    used to determine his competency were defective.     Competence to
    stand trial is a narrowly focused concept: a defendant may have all
    kinds of mental afflictions, but he can avoid trial only if he
    lacks "sufficient present ability to consult with his lawyer with
    a reasonable degree of rational understanding-and . . . a rational
    as well as factual understanding of the proceedings."      Dusky v.
    United States, 
    362 U.S. 402
    , 402 (1960).
    As already explained, after his arrest Brown was for
    several   years   confined   to    Bridgewater.    The   competency
    determination now before us was initially made in January 2001 and
    then reaffirmed after a hearing in March 2001 shortly before trial.
    The finding was made despite affidavits from Brown's counsel
    stating that Brown was "unable to consult with his attorneys with
    -13-
    a reasonable degree of rational understanding" and did not have a
    rational understanding of the proceedings against him.
    The defense expert, Dr. Price, based on examinations in
    February and March 2001, agreed.              She stated that Brown was
    suffering from chronic paranoid schizophrenia, was delusional,
    believed he was the Anti-Christ, and heard voices.             She said that
    Brown appeared to have deteriorated significantly since his last
    evaluation, was inattentive, and would have serious difficulties
    following the proceedings and preparing a defense.             She also said
    that       Brown   would   likely   substantially   improve   if   he   resumed
    medication.7
    The court's clinical psychologist evaluated Brown on
    March 7, and also found him incompetent.            He summarized his review
    of Brown's past evaluations as follows:
    [T]he prevailing clinical opinion is that
    [Brown] indeed can be competent, particularly
    when he is appropriately medicated. Under the
    influence of anti-psychotic medication his
    symptoms are significantly improved although
    never completely absent. . . .          [H]is
    competency can fluctuate under a number of
    different conditions.
    7
    Brown ceased taking medication in mid-February 2001 (before
    Dr. Price's first evaluation) so that he could "concentrate more
    easily on court proceedings"; another state judge ordered Brown be
    forcibly medicated on March 14, the day after the first day of the
    competency hearing. In Massachusetts, "a distinct adjudication of
    incapacity to make treatment decisions (incompetence) must precede
    any determination to override patients' rights to make their own
    treatment decisions."   Rogers v. Comm'r of the Dept. of Mental
    Health, 
    458 N.E.2d 308
    , 314-315 (Mass. 1983).
    -14-
    The psychologist reported that while Brown could respond
    well to short, concrete questions, he could not process questions
    that were longer or complex.           He concluded that Brown could
    understand   only   simple    concepts,   did   not   have   more   than   a
    superficial understanding of key legal processes (for example, he
    could name the two possible defenses as "Not guilty by Insanity"
    and "Not-There" but could not explain how he might choose between
    the two), and was not currently competent and would only worsen
    without medication.
    After receiving these reports, the judge ordered another
    evaluation by the Commonwealth's expert, a forensic psychiatrist.
    Dr. Annunziata met with Brown for two evaluations (both when Brown
    was still un-medicated), and testified that Brown was competent to
    stand trial. Dr. Annunziata said that while Brown did hear voices,
    they were not overly distracting, and that during the evaluation,
    Brown was able to concentrate and focus, had a good short-term
    memory,   and   showed   no   "gross   impairment     in   judgment."8
    Despite further defense testimony by Dr. Price after
    another brief interview with Brown, the trial judge ruled on March
    23, 2001, that Brown was competent, expressly relying solely on Dr.
    8
    However, Dr. Annunziata admitted that he had not reviewed
    Brown's medical records from his four-and-a-half years at
    Bridgewater, and that he did not ask Brown "many complex
    questions." He also testified that when Brown's attorney asked him
    a moderately complex question--specifically, whether Brown
    remembered three motions from a hearing the day before--Brown could
    not recall any.

    Annunziata's testimony, to which he gave "great weight and credit,"
    and his own observations of the defendant's conduct during the
    competency hearing.       On direct appeal, the SJC upheld Brown's
    competency, finding that determination within the province of the
    trial judge who heard the witnesses and observed the defendant.
    
    Brown, 872 N.E.2d at 722-23
    .       The question for us is whether this
    result is so clearly unreasonable that it should be set aside.
    Habeas challenges to state competency findings fail with
    remarkable regularity,        40 Geo. L.J. Ann. Rev. Crim. Proc. at 468
    n.1432 (2011) (citing cases), partly because habeas review is
    deferential    and   partly    because   the   trial    judge   has    seen the
    witnesses and the defendant. E.g., United States v. Figueroa-
    Gonzalez, 
    621 F.3d 44
    , 48 (1st Cir. 2010).                   The ability to
    understand the proceedings and assist counsel is both a matter of
    degree   and   one   in   which    trial   judges,      as   well     as   health
    professionals, have pertinent expertise.               See United States v.
    Ahrendt, 
    560 F.3d 69
    , 75 (1st Cir. 2009), cert. denied, 
    129 S. Ct. 2815
    .
    Here, Brown was surely impaired and, at the same time,
    all experts agreed that he at least possessed some understanding of
    the situation and some ability to reason about it and discuss
    issues with counsel.9     No one knows just how to measure precisely

    Mental illness, limited intelligence, emotional troubles and
    even amnesia as to pertinent events afflict many defendants, and
    they do not automatically prevent a defendant from being tried or

    that "sufficient present ability" to consult and understand of
    which the Supreme Court spoke in Dusky.            And, of course, a
    defendant who refuses medication can worsen his own condition until
    forcibly medicated; Brown, as it happens, was required to resume
    medication before his trial commenced.        See note 7, above.
    A raving lunatic may not be tried, however patently
    guilty and however hopeless his defense.       But Brown is in a gray
    area, somewhat impaired; and although "prejudice" is not part of
    the equation, it is hard to see what more Brown could have
    contributed to the thorough "all fronts" defense he received.
    Competence to stand trial, as defined by the Supreme Court, is
    decidedly a functional concept.          In the end, the state court
    finding was contestable, but it was not "unreasonable" under the
    deferential habeas standard.
    Brown   also   brings   a   procedural   claim   relating   to
    competency, saying that due process obliged the trial judge, as the
    defense requested, to review Brown's Bridgewater medical records
    and a tape of the Rogers hearing relating to forced medication, see
    note 7, above, before ruling on competency.        But one of Brown's
    experts testified at the hearing to the contents of his medical
    records and the other two had worked with him at Bridgewater; one
    pleading guilty. E.g., United States v. Rodríguez-León, 
    402 F.3d 17
    (1st Cir. 2005) (limited intelligence); Wright v. Sec'y for the
    Dep't of Corr., 
    278 F.3d 1245
    (11th Cir. 2002) (mental illness),
    cert. denied, 
    538 U.S. 906
    (2003); Wilson v. United States, 
    391 F.2d 460
    (D.C. Cir. 1968) (amnesia).

    of those had recommended that the Rogers hearing be held and
    testified there.    Brown has not pointed to any additional specific
    information (material or otherwise) that would have been revealed.
    In a further procedural challenge, Brown argues that
    after the court clinical psychologist found him incompetent on
    March 7, 2001, Massachusetts law mandated an additional extended
    observation   and   evaluation   at   Bridgewater   before   determining
    competency.   Mass. Gen. Laws ch. 123, § 15(b).      As the SJC pointed
    out, section 15(b)'s language is permissive, not mandatory, and it
    was reasonable to find that in light of the already-completed
    evaluations and extensive medical record, no further observation
    was "necessary."    
    Brown, 872 N.E.2d at 760
    .
    Voluntariness.    Finally, Brown claims that the district
    court violated due process by failing to hold a sua sponte hearing
    on the voluntariness of various statements made by Brown--seemingly
    statements he made between June 15 (the day before the killings)
    and June 26, 1996 (the day he was apprehended outside of Boston).
    These statements, which came into evidence through the testimony of
    various prosecution witnesses, are not directly quoted in Brown's
    brief, but are listed in a similar claim made in the SJC.        
    Brown, 872 N.E.2d at 725
    n.35 (listing statements).
    These included Brown asking Bobbitt to purchase a shotgun
    for him the day before the killings and indicating the one he
    wanted, and a denial of involvement to Bobbitt the day after;
    -18-
    statements made on June 18 (two days after the murders) to an
    acquaintance, Samuel Lewis, indicating Brown was talking and acting
    normally; and statements to the police officers who apprehended
    Brown after a traffic stop outside of Boston (including both
    answers to routine booking questions and Brown's statements when
    stopped for the traffic violation that he was returning from a
    party after dropping two girls at home).
    The judge allowed the statements in evidence over a
    defense objection after ruling (outside of the presence of the
    jury) they were made voluntarily, but ultimately instructed the
    jury that it should determine whether the statements were voluntary
    and must disregard any statement that was not voluntary.            Brown
    argues that the judge erred in not holding a separate sua sponte
    voluntariness inquiry in light of the evidence of his mental
    illness at the time the statements were made.
    Massachusetts law so requires under certain conditions,
    Commonwealth v. Sheriff, 
    680 N.E.2d 75
    , 79-80 (Mass. 1997), but the
    SJC held none was required here (and the trial court ultimately
    instructed   the   jury   to   determine   the    voluntariness   of    the
    statements), 
    Brown, 872 N.E.2d at 726-27
    . As we explained earlier,
    state law errors are not independent bases for habeas review.
    Given the context of the statements, it is far from clear that a
    federal constitutional     issue   could   be    made out.   See,      e.g.,
    Colorado v. Connelly, 
    479 U.S. 157
    (1986).
    -19-
    In   any   case,   the    most   critical   of   the   statements
    initially contested appear to be those made to Bobbitt while
    purchasing the gun for Brown, but the SJC held these statements--to
    which Bobbitt himself testified--were not subject to voluntariness
    analysis because they were "part and parcel of the crime."           
    Brown, 872 N.E.2d at 726
    .       The other statements of Brown, made to
    witnesses who testified to his seeming rationality, merely provided
    the basis for their own assessment and--in a debatable case--are
    admissible under state law.
