Right To Disclosure Of Exculpatory And Impeachment EvidenceQuestion 1 of 12

After the defendant's conviction for assault, he moved for post-conviction relief, arguing that the prosecutor had withheld three items: a bystander's statement that the attacker was taller than the defendant, a medical report saying the victim's injuries could have been caused by a fall, and a police report showing a key prosecution witness had given a prior inconsistent statement. The post-conviction court reviewed each item individually, concluded that none would probably have changed the verdict, and denied relief.

Which of the following is the most accurate assessment of the court's ruling?

The ruling is correct because each piece of suppressed evidence must be evaluated separately to determine whether it would have changed the verdict.

The ruling is correct unless the defendant made a specific pretrial request for the suppressed items, in which case the failure is automatic.

The ruling is incorrect as to the prior inconsistent statement only, because the other items were not favorable evidence under the due-process disclosure rule.

The ruling is incorrect because materiality must be assessed by considering the cumulative effect of all suppressed evidence.

Question 1

Which of the following is the most accurate assessment of the court's ruling?

The ruling is correct because each piece of suppressed evidence must be evaluated separately to determine whether it would have changed the verdict.
The ruling is correct unless the defendant made a specific pretrial request for the suppressed items, in which case the failure is automatic.
The ruling is incorrect as to the prior inconsistent statement only, because the other items were not favorable evidence under the due-process disclosure rule.
The ruling is incorrect because materiality must be assessed by considering the cumulative effect of all suppressed evidence. (correct answer)

Explanation: Whenever you see a question about a prosecutor's failure to disclose evidence, think Brady and the materiality standard. Suppressed evidence is material if there is a reasonable probability that, had it been disclosed, the result of the proceeding would have been different. Critically, that materiality determination is not made piece-by-piece; you must look at all the suppressed evidence together. the whole picture). " The post-conviction court here made exactly that mistake: it reviewed each item individually, decided none alone would have changed the verdict, and denied relief. That is legally wrong. The correct assessment is that the ruling is incorrect because materiality must be assessed by considering the cumulative effect of all suppressed evidence. The bystander statement, the medical report, and the prior inconsistent statement might each seem minor alone, but together they could substantially undermine the prosecution's case and create reasonable doubt. The choice saying the ruling is correct because each piece must be evaluated separately is wrong for that reason—separate evaluation is precisely the error. The choice saying the ruling is correct unless the defendant made a specific pretrial request, in which case failure is automatic, is also wrong: the prosecution's duty to disclose favorable material evidence exists regardless of a request, and even after a request, materiality still must be shown—there is no automatic reversal. The choice saying the ruling is incorrect as to the prior inconsistent statement only because the other items were not favorable misreads Brady too: all three items were favorable in the sense that they could impeach the prosecution case or cast doubt on guilt, including the bystander observation and medical report. So remember: in Brady cases, always evaluate suppressed evidence cumulatively—one plus one can equal three.

Question 2

Before trial, the prosecutor had documents showing that the government's main witness, a confidential informant, had been paid a substantial fee and had a pending charge. The prosecutor did not disclose them until after the informant finished direct examination. Defense counsel requested a continuance to investigate and to recall the witness for an effective cross-examination, but the judge denied it. The witness was not recalled, and the defendant was convicted.

Which of the following is most accurate about whether the defendant's due-process right to disclosure was violated?

The right was violated, because the disclosure came too late for effective use and the evidence was material. (correct answer)
The right was not violated, because the evidence was disclosed at trial and the judge had the opportunity to remedy any prejudice.
The right was not violated, because Brady requires only that disclosure occur before the close of evidence.
The right was violated, because any late disclosure of impeachment evidence is automatically a due process violation.

Explanation: Whenever you see a question about delayed disclosure of evidence, remember that Brady is not just about what the prosecution knows—it is about when the defense can use it. The due-process right to disclosure is violated when the prosecution suppresses evidence that is both material to guilt or punishment and favorable to the accused, and the key word in this fact pattern is "effective use." The prosecutor's timing here doomed the trial. Although the documents were technically turned over before the verdict, they arrived after the informant's direct examination, and the judge's denial of a continuance meant the defense never got a meaningful chance to investigate the fee or the pending charge or to cross-examine the witness about them. Because this impeachment evidence was material—it went to the credibility of the government's "main witness"—the late disclosure deprived the defendant of a fair trial, so the right was violated. The wrong answers each miss this central timing requirement. The choice saying "the right was not violated, because the evidence was disclosed at trial" ignores the fact that disclosure must be timely enough for the defense to use it; simply handing it over during trial is not enough. Likewise, the choice claiming "Brady requires only that disclosure occur before the close of evidence" is a common trap—it treats the rule as a mere filing deadline, but Brady is about fairness, not a clock. Finally, the choice asserting that "any late disclosure of impeachment evidence is automatically a due process violation" overstates the rule; the evidence must also be material to the outcome, and not every late disclosure rises to that level. Your study tip: always ask "Could the defense have used this evidence effectively?" If the answer is no, the disclosure was effectively a non-disclosure.

Question 3

After the defendant was convicted of homicide, he learned that, before trial, a confidential informant had told the prosecutor that a now-deceased gang member had admitted to the killing. The informant refused to testify, and the prosecutor did not disclose the statement, believing it was inadmissible hearsay. The defendant argued that the statement could have led him to evidence supporting a third-party-culpability defense. The state responded that the statement was inadmissible and therefore outside Brady.

Which of the following is most accurate?

The state is correct because Brady applies only to evidence that would be admissible if offered by the defense at trial.
The state is incorrect because inadmissible evidence may be favorable if it could lead to admissible evidence, and materiality is assessed in context. (correct answer)
The state is correct because the informant refused to testify, so the statement could not be used and was therefore not favorable.
The state is not correct because any favorable evidence must be disclosed regardless of whether it is material.

Explanation: Whenever you see a Brady issue, focus on the three elements: the evidence is favorable to the defense, suppressed by the prosecution, and material to guilt or punishment. A common trap is equating "favorable" with "admissible." Here, the statement by the deceased gang member was inadmissible hearsay, but it could still be favorable because it could lead the defense to admissible evidence supporting a third-party-culpability defense. Materiality is assessed in the full context of the trial, not by looking at the statement in isolation. So the state is incorrect. Why the other choices miss the mark: The claim that Brady applies only to admissible evidence is too narrow—Brady protects a fair trial, and usable leads count. The claim that the informant's refusal to testify makes the statement unusable and therefore not favorable confuses trial value with investigative value; the statement's worth is as a lead. And the claim that any favorable evidence must be disclosed regardless of materiality overstates the duty—Brady only requires disclosure of material evidence, though the bar here is low. Your takeaway: when a prosecutor fails to disclose, ask "Is it favorable?" and "Is it material?"—not "Would the judge admit it?" Admissibility is not the test; usefulness is.

Question 4

A jailhouse informant testified that the defendant confessed to arson. Before trial, the prosecutor had a letter recommending a reduced sentence for the informant in exchange for his testimony but failed to turn it over. The defendant's own investigator, however, had independently obtained a copy of the letter from the jail's records and gave it to defense counsel. Defense counsel used the letter to cross-examine the informant about his deal. The defendant was convicted.

Did the prosecutor's failure to disclose the letter violate the defendant's due-process right?

Yes, because the prosecutor's disclosure duty is absolute and does not depend on whether the defense already had the evidence.
Yes, because the letter was impeachment evidence and the prosecutor was obligated to disclose it even if the defense obtained it elsewhere.
No, because the defense already possessed the letter and used it at trial, so the failure to disclose was not material. (correct answer)
No, because impeachment evidence is not covered by the due-process right to disclosure.

Explanation: Whenever you see a due-process disclosure question, think Brady: the prosecution must turn over evidence that is favorable to the defense and material to guilt or punishment. Impeachment evidence qualifies as favorable, but the key is materiality — the failure to disclose only violates due process if it undermines confidence in the trial outcome. Here, the letter was favorable impeachment evidence, but the defense already had it through its own investigator and used it to cross-examine the informant. Because the jury heard the impeachment, the prosecutor's failure to turn it over did not deprive the defendant of a fair trial. No reasonable probability exists that the result would have changed; the suppression was therefore not material. The choice claiming the prosecutor's duty is "absolute and does not depend on whether the defense already had the evidence" goes too far — Brady protects against unfair trials, and independent possession eliminates the unfairness. Similarly, the choice saying the prosecutor was obligated "even if the defense obtained it elsewhere" ignores that materiality requires actual prejudice from non-disclosure. The choice saying "impeachment evidence is not covered" is flatly wrong: Brady includes impeachment evidence when material. Your study tip: always run the three Brady elements — favorable, suppressed, material. If the defense already possessed the evidence and used it, the "suppressed" and "material" prongs collapse, and there is no violation.

Question 5

The defendant was charged with murder. The state's evidence included a surveillance video that clearly showed the defendant firing the fatal shot and two eyewitnesses who identified him. A third prosecution witness, who testified only that she saw the defendant arguing with the victim outside a bar an hour before the shooting, had a prior conviction for filing a false police report. The prosecutor failed to disclose the conviction. The defendant was convicted.

Which of the following is most accurate about whether the failure to disclose violated the defendant's due-process right?

It did not, because a conviction for filing a false police report does not bear on a witness's truthfulness.
It did not, because the undisclosed impeachment evidence was not material in light of the video and other identifying witnesses. (correct answer)
It did, because the prosecutor must disclose all evidence that could be used to impeach any prosecution witness.
It did, because the prior conviction was admissible impeachment evidence and the prosecutor had no discretion to withhold it.

Explanation: Whenever a question asks whether a prosecutor's failure to disclose evidence violated due process, think Brady v. Maryland. Brady is not a blanket discovery rule: the prosecutor must disclose evidence favorable to the accused only when that evidence is material — meaning there is a reasonable probability that disclosure would have changed the outcome. Here, the undisclosed prior conviction could have been used to impeach the third witness, so it qualifies as favorable impeachment evidence. But materiality is the decisive issue. That witness only testified that she saw an argument outside a bar an hour earlier; she did not place thedefendant at the shooting itself. And the state had a surveillance video clearly showing him firing the fatal shot, plus two eyewitnesses who identified him. Given that evidence, there is no reasonable probability that impeaching this peripheral witness would have led to a different verdict. So the failure to disclose did not violate due process. The suggestion that the conviction does not bear on truthfulness is mistaken:a conviction for filing a false police report ordinarily does reflect dishonesty. But even if it did not, the test is materiality, not mere relevance. Similarly, the claim that the prosecutor must disclose all evidence that could impeach any prosecution witness is too broad; Brady requires disclosure only of material favorable evidence, not every conceivable impeachment exhibit. And the argument that the conviction was admissible impeachment evidence means there was no discretion to withhold itconfuses admissibility with constitutional disclosure obligations: even admissible impeachment evidence need not be disclosed unless its suppression undermines confidence in the outcome. A useful takeaway: ina Brady question, first ask whether evidence is favorable, then ask whether it is material. A violation occurs only when the answer to both is yes.

Question 6

After a jury convicted the defendant of first-degree murder, the same jury was to decide between life and death. A psychologist's report in the prosecutor's file concluded that the defendant had an intellectual disability and was highly susceptible to coercion by co-offenders. The prosecutor did not disclose the report. Defense counsel presented only the defendant's mother's testimony about his difficult childhood. The jury imposed a death sentence. The defense later discovered the report.

Which of the following is most accurate regarding the prosecutor's failure to disclose the report?

No, because Brady applies only to evidence bearing on guilt, not to evidence considered during the sentencing phase.
No, because the report was not admissible in the sentencing proceeding and therefore could not affect the jury's decision.
Yes, if the report was favorable and there is a reasonable probability that it would have led to a different sentence. (correct answer)
Yes, because the prosecutor is required to disclose all evidence in the file during the sentencing phase.

Explanation: Whenever you see a prosecutor's failure to disclose evidence, think Brady: suppression of favorable evidence violates due process if the evidence is material. And remember that Brady is not limited to guilt proceedings—it applies with full force to capital sentencing, because the jury's death decision is part of the punishment determination. Here, the psychologist's report concluding intellectual disability and susceptibility to coercion is plainly favorable mitigation evidence. If there is a reasonable probability that disclosing it would have produced a different sentence, the death sentence cannot stand. That is the correct standard: favorable, material, suppressed. The first wrong answer ("Brady applies only to evidence bearing on guilt") reflects a common misconception—Brady material includes evidence relevant to punishment,sentencing, if not guilty determination. The second ("report was not admissible and therefore could not affect decision") misstates Brady: evidence need not be admissible itself; it can be useful for investigation, impeachment, or leading to admissible expert testimony, and materiality asks about effect on outcome, not threshold admissibility. The third ("required to disclose all evidence in the file") overstates the duty—the prosecutor must disclose favorable/material evidence, not everything in the file regardless of relevance. The right answer keeps the focus where Brady actually puts it: whether the withheld report was favorable sufficient that confidence in the death sentence is undermined. For strategy, when you see Brady questions, ask first: guilt or punishment? favorable? material? That structure will usually lead you to thecorrect choice.

Question 7

Before trial, defense counsel specifically requested 'any and all statements by prosecution witnesses that are inconsistent with their expected trial testimony.' The prosecutor failed to disclose a police report in which a key eyewitness told an officer that the perpetrator was 'stocky and about 5 feet 6 inches,' while the witness later identified the defendant, who was 6 feet 3 inches and thin. At trial, the witness identified the defendant. The defendant was convicted. On appeal, the court finds the suppressed statement was material.

Which of the following statements about the specific request is most accurate?

Because the request was specific, the failure to disclose is a per se due process violation without a separate materiality showing.
Because the request was specific, the prosecutor's failure to disclose is measured by whether the defendant could have used the statement, not whether it was material.
The specific request is irrelevant because the prosecutor's duty to disclose exists only when the defense has made a request.
The specific request may inform the materiality inquiry, but the defendant must still show a reasonable probability that disclosure would have changed the result. (correct answer)

Explanation: When you see a prosecutorial-disclosure issue, anchor yourself in Brady due process: the core question is always materiality. A specific defense request can make the prosecutor's omission more telling, but it does not replace the constitutional standard. Here, the police report undercutting the eyewitness's description could impeach that witness, and the court found it material—so the request helped show why the evidence mattered. But the defendant still had to prove a reasonable probability that disclosure would have changed the result. The specific request may inform the materiality inquiry; it does not eliminate it. That is why the statement saying the request "may inform the materiality inquiry, but the defendant must still show a reasonable probability" is correct. The trap in "failure to disclose is a per se due process violation without a separate materiality showing" is that no automatic violation exists—materiality is the constitutional threshold. Likewise, "measured by whether the defendant could have used the statement, not whether it was material" is wrong: usefulness is far broader than materiality, and the Supreme Court has required a reasonable probability of a different outcome. Finally, "specific request is irrelevant because the prosecutor's duty exists only when the defense has made a request" gets the law backwards—the duty exists even without a request, but a request is not irrelevant; it can sharpen the materiality analysis. On the exam, remember: a specific request is a factual factor, not a separate legal standard. Keep reasonable probability at the center.

Question 8

Police investigating a murder interviewed a bus driver who said she saw the defendant at a diner twenty miles from the murder scene at the time of the murder. The detective included this in his report but never told the prosecutor. The prosecutor, unaware of the report, did not disclose it. The defendant made no discovery request. At trial, the state's case was built on a single eyewitness. The defendant was convicted and later learned of the bus driver's statement.

Was the defendant's due-process right to exculpatory evidence violated?

No, because the prosecutor cannot be expected to disclose evidence she did not know existed.
No, because the defendant made no request for exculpatory evidence.
Yes, because the detective's knowledge is attributed to the prosecution team and the statement was favorable and material. (correct answer)
Yes, but only if the detective deliberately hid the report from the prosecutor.

Explanation: Whenever you see a due-process claim about undisclosed evidence, think Brady v. Maryland: the prosecution must disclose evidence favorable to the defendant that is material to guilt or punishment—even without a defense request. The duty covers the whole prosecution team, including police. Here, the bus driver's statement placed the defendant twenty miles away at the time of the murder, directly undermining the single eyewitness. That is favorable and material. Because the detective knew about it, his knowledge is imputed to the prosecutor. So the defendant's due-process right was violated. The choice saying "the prosecutor cannot be expected to disclose evidence she did not know existed" is a trap: ignorance may explain the failure, but it does not excuse it when a team member knew. The choice saying "the defendant made no request" is also wrong—Brady applies even without a request. And the choice saying "only if the detective deliberately hid the report" misstates the rule: the prosecution's good or bad faith is irrelevant; the question is whether the evidence was favorable and material. Your takeaway: in Brady questions, check three things—favorability, materiality, and whether anyone on the prosecution team knew. If all three are present, the duty was violated, regardless of intent or defense requests.

Question 9

The defendant was convicted of burglary. At trial, the state presented evidence that the defendant's fingerprint was found on a window of the burglarized store, that a surveillance video showed him inside the store during the burglary, and that stolen merchandise was later found in his apartment. The state also called a jailhouse informant who testified that the defendant had confessed to the burglary while they were in custody together. The informant did not mention any deal. The lead police detective had, without the prosecutor's knowledge, promised the informant that he would recommend leniency on an unrelated pending charge if the informant testified. The prosecutor did not disclose any deal. After the conviction, the defendant learned of the detective's promise and moved for a new trial.

Should the court grant the motion?

No, because the promise was not material; in light of the fingerprint, video, and stolen merchandise, there is no reasonable probability of a different result. (correct answer)
Yes, because the informant's failure to disclose the promise made his testimony false, and the prosecution has a duty to correct false testimony even if the prosecutor did not know it was false.
No, because the prosecutor did not know of the promise, and a police detective's promise to recommend leniency is not attributable to the prosecution.
Yes, because the detective's promise was favorable impeachment evidence, the prosecutor is charged with knowledge of evidence known to the police, and the failure to disclose it is automatically reversible.

Explanation: When you see a question about a prosecutor's failure to disclose evidence, your mind should go immediately to the Brady/Giglio framework: the defendant must show (1) the evidence is favorable—often impeachment evidence (2) the prosecution—including the police team—knew or constructively knew of it, andd (3) the evidence is material, meaning there is a reasonable probability the outcome would have been different. Here, the detective's promise to the informant was indeed favorable impeachment evidence, and the prosecutor is generally charged with knowledge of evidence known to the police. So the nondisclosure isnot automatically excused bythe prosecutor's ignorance. But the key failure is materiality. With the defendant's fingerprint on the window, surveillance video placing him inside, and stolen merchandise in his apartment, the informant's testimony was cumulative; his impeachment would not create a reasonable probability of acquittal. Thus the motion should be denied. The "informant's testimony was false" argument misses the mark: the record does not show the informant testified falsely, only that he failed to mention a deal; any contradiction would need to come out on cross-examination. The"detective's promise is not attributable" argument also fails because police knowledge counts for Brady purposes. And the"automatic reversal" argument is wrong because Brady violations are not per se reversible—materiality is always required. Remember the exam trap: do not stop after finding favorable, undisclosed evidence. Always complete the materiality analysis. Overwhelming independent guilt evidence can make a nondisclosure harmless.

Question 10

At the defendant's trial for burglary, the victim identified the defendant as the person she saw leaving her apartment. A police report contained a neighbor's statement that she saw a different person leaving the apartment with a television. The prosecutor did not disclose the report because the defense never requested discovery. The defendant was convicted. The neighbor's statement was credible and would have supported a misidentification defense.

Which of the following is most accurate about whether the defendant's due-process right was violated?

No, because the defendant's failure to request discovery waives any right to exculpatory evidence.
No, because the neighbor's statement did not conclusively prove the defendant's innocence.
Yes, because the prosecutor must disclose material exculpatory evidence even without a request. (correct answer)
Yes, but only if the prosecutor knew the neighbor's statement was true.

Explanation: Whenever you see a prosecutor withholding evidence, think Brady v. Maryland: the prosecution must disclose material exculpatory evidence even if the defense never asks. The neighbor's statement—that a different person left with the television—directly supports a misidentification defense. Because it was credible and could have changed the outcome, it was material. The prosecutor's failure to disclose it violated the defendant's due-process rights. The choice saying "the defendant's failure to request discovery waives any right" is wrong because Brady imposes an independent duty on the prosecutor; the defense has no obligation to request exculpatory evidence. The choice saying "the statement did not conclusively prove innocence" sets the bar too high—materiality does not require proof of innocence, only a reasonable probability of a different result. Finally, the choice saying "but only if the prosecutor knew the statement was true" misunderstands the rule. The duty is based on whether evidence is favorable and material, not on the prosecutor's subjective belief about its truth; credibility is for the jury, not the prosecutor, to decide. On exam day, when a prosecutor fails to disclose evidence that could help the defense, the key is materiality. Don't be distracted by "no request," "not conclusive," or "prosecutor doubted it"—those are all traps. The due-process violation occurs when withheld evidence could reasonably put the verdict in doubt.

Question 11

At the defendant's trial for unlawful possession of a firearm, the only witness who testified that the defendant possessed the gun was a police officer. Before trial, the prosecutor learned that the officer was under federal indictment for submitting false travel vouchers. The prosecutor did not disclose the indictment to the defense. On cross-examination, the officer denied having any pending charges, and the prosecutor remained silent. The defendant was convicted and later learned of the indictment.

Which of the following statements is most accurate about whether the defendant's due-process right to disclosure was violated?

No, because the indictment concerned only the officer's own financial conduct and did not directly exonerate the defendant.
No, because the officer's denial, rather than the prosecutor's silence, was the cause of any prejudice to the defense.
Yes, but only if the prosecutor knew the officer's denial was false before it was made.
Yes, because the undisclosed indictment was impeachment evidence material to the credibility of the only witness against the defendant. (correct answer)

Explanation: Whenever you see a due-process disclosure question, think Brady: the prosecution must disclose evidence favorable to the accused, including evidence that could impeach a government witness, if it is material to guilt or punishment. Here, the undisclosed federal indictment was exactly that. The officer was the only witness who said the defendant possessed the gun, so his credibility was central. A jury might well have doubted him if it knew he was facing pending charges for dishonesty. That makes the withheld impeachment evidence material, so the failure to disclose violated due process. The first wrong answer, "the indictment concerned only the officer's own financial conduct," misses that impeachment evidence does not need to directly exonerate the defendant. Evidence that undermines the only prosecution witness is favorable. The second wrong answer, blaming "the officer's denial" rather than the prosecutor's silence, misunderstands the prosecutor's independent duty: disclosure was required before trial, and silence during the false denial only compounded the violation. The third wrong answer, requiring that the prosecutor "knew the officer's denial was false," confuses Brady with the separate rule against knowingly presenting false testimony. A Brady violation does not require knowledge that the witness would lie; it requires only that favorable, material evidence was withheld. Remember this pattern: when one witness is decisive, ask what the defense could use to attack that witness. If the prosecution has it and stays silent, due process is violated.

Question 12

A prosecutor received a laboratory report before trial showing that DNA under the victim's fingernails did not match the defendant, even though the state's theory was that the defendant had fought with and scratched the victim. The prosecutor inadvertently failed to produce the report. At trial, the state relied on the victim's identification and testimony about motive; no DNA evidence was introduced. The defendant was convicted. The report was later discovered.

Which of the following is most accurate about the due-process right to disclosure?

A violation occurred if the DNA report was favorable and there is a reasonable probability that disclosure would have changed the outcome. (correct answer)
No violation occurred because the DNA report was not introduced at trial and therefore could not be material.
A violation occurred because any undisclosed DNA evidence in the prosecution's file automatically requires reversal.
No violation occurred because the prosecutor's failure was inadvertent rather than deliberate.

Explanation: Whenever you see a due-process disclosure question, think Brady: the suppressed evidence must be favorable, material, and suppressed by the state. Importantly, the prosecutor's inadvertent failure to produce a lab report counts as suppression—bad faith is not required. The DNA nonmatch was exculpatory because it undermined the state's theory of a physical struggle with the victim, so the key question is materiality. Why does your correct choice work? The report is material if there is a reasonable probability that disclosure would have changed the outcome. That is exactly the standard: favorable evidence plus a reasonable probability of a different result. Even though no DNA evidence is introduced, undisclosed evidence can still be material because its absence may have altered jury deliberations, cross-examination, or defense strategy. The report need not have been admitted—the question is what would likely happen if it were available. Now the wrong choices. "No violation occurred because the DNA report was not introduced"—that confuses actual admission with materiality; Brady is about whether the non-disclosure prejudiced the trial, not whether the evidence was offered. "Any undisclosed DNA evidence automatically requires reversal" overstates: automatic reversal applies only rarely, and non-material Brady violations do not. Finally, "no violation because the failure was inadvertent" mistakes the doctrine: Brady liability turns on suppression, not intent, so even an honest mistake can violate due process if the evidence is favorable and material.ice Study takeaway: in any disclosure question, ask yourself (1) favorable?(2) suppressed?(3) material?—and never let prosecutorial intent excuse indifference.
