Texas is preparing to execute Kwame Rockwell (pictured)—a severely mentally ill death-row prisoner suffering from schizophrenia—on October 24, 2018, after the Tarrant County District Court rejected his lawyers’ assertions that he is incompetent to be executed. On October 16, Rockwell’s lawyers filed an appeal in the Texas Court of Criminal Appeals arguing that the trial court abused its discretion in rejecting his competency claim without an evidentiary hearing and without providing funds for him to obtain a competency evaluation. The appeal argues that Rockwell “does not understand he is to be executed,” “has no understanding that he was convicted of capital murder and sentenced to death,” and “does not comprehend that he has been incarcerated on death row since 2012 or even that he is presently incarcerated in a Texas prison.”
The U.S. Supreme Court ruled in Ford v. Wainwright (1986) that the Eighth Amendment prohibits the execution of prisoners who have become “insane”—which the Court defined as being “unaware of the punishment they are about to suffer and why they are to suffer it.” In 2007, in the Texas case of Panetti v. Quarterman, the Court explained that a prisoner whose delusions prevent him from having a “rational understanding” of these circumstances is incompetent to be executed. A neuropsychologist who examined Rockwell in July reported that Rockwell said he saw snakes and demons that were inside of him, appeared to be hearing voices, and, in response to a question about his name, said “my name is God.” The doctor’s affidavit said Rockwell “does not understand or appreciate where he is, the nature of his charges, why he is in prison, or the nature of his punishment.” Rockwell’s lawyers also presented the court with evidence of his significant family history of psychotic illness, including twelve family members across three generations of his family with mental illness diagnoses, and Rockwell’s own mental illness in childhood and as an adult. Citing prison records, the appeal states: “Rockwell has consistently experienced intense hallucinations and auditory delusions, despite spending the majority of his sentence on four or more antipsychotic medications concurrently. He is haunted by snakes and demons. No medications have been able to eliminate his hallucinations or delusions.”
The U.S. Supreme Court has never categorically excluded people with serious mental illness from being sentenced to death or executed. A 2014 poll found that Americans by a two-to-one margin oppose executing people with mental illness. Several states have recently considered, but not adopted, legislation to bar the death penalty for people with severe mental illnesses. Rockwell’s trial lawyer did not present to the jury mitigating evidence of Rockwell’s schizophrenia or his family’s history of psychotic mental illness. Nonetheless, the Texas state and federal courts denied Rockwell’s claim that he had been provided ineffective representation at sentencing. In an opinion piece for Pacific Standard, David M. Perry compared the courts’ treatment of Rockwell’s case with the recent stay of execution granted to fellow Texas prisoner Juan Segundo. Segundo was granted a stay so the Tarrant County court could reconsider his claim of intellectual disability after the Supreme Court had ruled that the standard Texas had previously applied unconstitutionally risked that some people with intellectual disability would still be executed. “America still doesn't have clear protections for people with severe mental illness,” Perry explains. “These two cases in Texas remind us of the unfortunate diagnostic limitations that protect only some people with disabilities from the death penalty.”
As Seminole County prosecutors seek the death penalty against Clemente Javier Aguirre-Jarquin a second time despite substantial evidence implicating another suspect, the Florida judge who initially sentenced Aguirre-Jarquin to death now says he should not be convicted. Retired Judge O.H. Eaton (pictured), who presided over Aguirre-Jarquin’s double-murder trial in 2006, said he now believes that the case is a “poster child” for the flaws in the death penalty system. “The evidence I heard during the trial [in 2006] substantiated the verdict,” Eaton told the Orlando Sentinel. “The evidence I’ve heard now does not. ... If I knew then what I know now, I probably would have ordered the jury’s verdict overturned.”
Aguirre-Jarquin, an undocumented Honduran immigrant, was convicted of murdering his next-door neighbors, Cheryl Williams and her mother Carol Bareis, who were stabbed more than 130 times. Eaton imposed death sentences for both murders, based on non-unanimous 7-5 and 9-3 jury recommendations for death. Aguirre-Jarquin’s post-conviction lawyers later discovered that the mentally ill daughter and granddaughter of the victims, Samantha Williams—who had provided eyewitness testimony against Aguirre-Jarquin—had confessed to at least five different people that she had killed her relatives. She told one person: “I’m crazy, I’m evil and I killed my grandmother and my mother.” DNA results from blood evidence at the crime scene also implicated Williams. The Innocence Project, which assisted in Aguirre-Jarquin’s post-conviction representation, found that “[n]one of the DNA found on the 84 items that were tested matched Aguirre,” but was a match to Williams and the two victims. Eight bloodstains from Williams were found in four different rooms, each, the Innocence Project said, ”inches away from the victims’ blood." Based on this evidence, the Florida Supreme Court in 2016 unanimously overturned Aguirre-Jarquin's conviction. Seminole County prosecutors nonetheless decided to retry Aguirre-Jarquin, simultaneously arguing that Williams’s mental health problems make her confessions unreliable, but relying upon her testimony against Aguirre-Jarquin in his 2006 trial. They also argue that Aguirre-Jarquin—who says he went to his neighbors’ home to get beer, found their bodies, and tried to revive them—attempted to hide clothing with the victims’ blood on it, and did not call police after discovering his neighbors had been killed. Aguirre-Jarquin said he did not call the police because he feared deportation because of his undocumented status.
Florida has more death-row exonerations than any other state, with 27. Ninety percent of those exonerations came in cases in which one or more jurors had recommended a life sentence.
"Has the death penalty evolved into an anachronism?" asked a panel at the August 2, 2018 American Bar Association Annual Meeting in Chicago. Moderator Ronald Tabak, chair of the ABA Death Penalty Committee, and panelists Cardinal Blase J. Cupich of the Archdiocese of Chicago; Karen Gottlieb, co-director of the Florida Center for Capital Representation; Meredith Martin Rountree, senior lecturer at the Northwestern Pritzker School of Law; and Robert Dunham, executive director of the Death Penalty Information Center sought to answer that question through a discussion of the last forty years of American death-penalty history and the evolution of the Catholic Church's moral teachings on the subject. The panelists' consensus: the death sentences imposed upon many of the death-row prisoners executed in the past would be unconstitutional today, and most of the prisoners now being executed would not be sentenced to death if they were tried today.
The panel serendipitously took place on the same day that Pope Francis announced that the Catholic Church had formally revised its Catechism to deem the death penalty "inadmissible." Cardinal Cupich described the evolution of the Catholic Church's teachings on capital punishment, with an emerging focus on the concept of the dignity of human life. "Our assertion that the value of a human life does not depend upon an individual’s quality of life or age or moral worth must apply in all cases," he said. "For if we protect the sanctity of life for the least worthy among us, we surely witness to the need to protect the lives of those who are the most innocent, and most vulnerable." Karen Gottlieb highlighted how accidents of timing can result in unconstitutional executions, using Florida as an example of how numerous defendants with valid constitutional claims have been executed before courts issue rulings that would have barred their execution and how recent court rulings will permit the execution of more than 150 death-row prisoners who the state court acknowledges were sentenced under unconstitutional procedures. Meredith Martin Rountree discussed how American death-penalty law has evolved to exempt youthful offenders and individuals with intellectual disability and provided examples of current death-penalty practices—including the execution of offenders aged 18-21 and of people with severe mental illness—that could likely be banned in the future. Robert Dunham explained the "sea change in America’s attitudes about capital punishment" over the past twenty-five years and the reasons behind the accompanying broad nationwide decline in death-penalty usage over that period. He provided examples of more than 250 people who have been executed despite constitutional violations that would have invalidated their death sentences today and the estimated hundreds of others who were unconstitutionally sentenced to death but executed nevertheless because of procedural technicalities that prevented federal courts from enforcing constitutional protections in those cases.
A transcript of the proceedings, with updates from the panelists, was released by the ABA's Section of Civil Rights and Social Justice in late September 2018 and recently posted on the DPIC website.
Most of the 142 prisoners on North Carolina’s death row were convicted under obsolete and outdated death-penalty laws and would not have been sentenced to death if tried today, according to a new report by the Center for Death Penalty Litigation. The report by the Durham-based defense organization, titled Unequal Justice: How Obsolete Laws and Unfair Trials Created North Carolina’s Outsized Death Row, says that nearly three-quarters of the prisoners on the nation’s sixth-largest death row were tried and sentenced before the state enacted significant reforms in prosecution, defense, and trial practices. “[I]f these people on death row had been tried under modern laws, most of them would be serving life without parole sentences instead of facing execution,” said Gretchen Engel, the Center’s executive director.
Seventy-three percent of the men and women on North Carolina’s death row (103 prisoners) were tried and sentenced to death before July 2001, when North Carolina repealed a 1990s-era law that had required prosecutors to pursue the death penalty in every aggravated murder case, irrespective of reasons that might call for mercy, and created a statewide office to represent indigent defendants in capital trials and appeals. North Carolina was the only state in the country that denied prosecutors the discretion to decide when to seek the death penalty, and as a result, there were more than fifty capital trials in the state each year, including cases involving defendants who were seriously mentally ill or intellectually disabled or were comparatively minor participants in a murder. Capital trials fell to an average of sixteen per year in the decade following the change. The creation of the capital defender office that same year dramatically improved the quality of representation, and further reduced the number of cases in which death verdicts were returned. Since then, North Carolina has enacted additional reforms aimed at ensuring fairer trials in capital cases. In October 2004, the state became the first in the country to require prosecutors to make all witness files, police reports, other investigative records, and physical evidence available to capital defendants prior to trial. In 2008, it adopted a series of eyewitness identification and interrogation protocols designed to prevent mistaken identifications and false or coerced confessions.
The report states that during the 1990s, before the reforms were enacted, “courtrooms were dominated by prosecutors like Ken Honeycutt in Stanly County, who celebrated new death sentences by handing out noose lapel pins to his assistant prosecutors.” “Today,” Engel said, “we are living in a different world .... Public support for the death penalty is at a 50-year low, and North Carolina has stopped executing people. Juries now see life without parole as a harsh and adequate punishment for the worst crimes.” That, however, has produced its own historical inequities. In terms of moral culpability, Engel said, the defendants facing trial in 1995 and 2015 “are equal. And yet, one of them is being subjected to execution and other is not and that is an unfairness that as a fair society, we can not tolerate.”
A Nebraska county has raised property taxes on its residents and asked the state legislature for a bailout to help pay a $28.1 million civil judgment it owes to six men and women wrongly convicted of rape and murder after having been threatened with the death penalty. The so-called “Beatrice Six” (pictured) successfully sued Gage County for official misconduct that led to their wrongful convictions in the 1985 rape and murder of Helen Wilson. The large damages award exceeds Gage County's entire annual budget by $1 million. This year, Gage County Supervisors passed a property tax increase of 11.76 cents per $100 of valuation—the maximum increase allowed without putting the issue to voters. The tax increase is expected to generate about $3.8 million next year, but county leaders worry about its impact on residents and have announced plans to ask lawmakers and Governor Pete Ricketts for state funding or a loan to help pay the civil judgment. Greg Lauby, a former attorney who organized residents to seek solutions to the problem, said, “If we continue on the path we’re on with no assistance from the state, it will drive at least some farmers to bankruptcy. We have homeowners who are struggling to put food on their table and clothe their children, and that’s an amount that will make a difference.”
Five of the Beatrice Six exonerees—James Dean, Kathy Gonzalez, Debra Shelden, Ada JoAnn Taylor, and Tom Winslow—agreed to plea bargains or pled no contest after prosecutors threatened them with the death penalty. A sixth, Joseph E. White, maintained his innocence, but was convicted at trial based on false testimony about his alleged involvement in the crime. The six were exonerated by DNA evidence in 2008 after spending a combined 70 years in prison. The damages were awarded by a federal jury in 2016, just months before Nebraska voters passed a referendum to overturn the legislature's 2015 abolition of the death penalty and reinstate capital punishment. The county is responsible for the payment because prosecutors are immune from liability for wrongful convictions, and the sheriff involved in the case died in 2012. State Senator Ernie Chambers—one of the leaders of the death-penalty repeal efforts—said he opposes a state bailout. “This was strictly a county matter,” Chambers said. “They made their bed, now they have to sleep in it.” He added that, despite widespread coverage of the exonerations, Gage County voters overwhelmingly supported the reinstatement of the death penalty in 2016. “They haven’t learned a thing,” he said. Ultimately, as the McCook (Nebraska) Gazette wrote in an October 8, 2018 editorial, “[t]he Beatrice Six case and others like it spotlight the need to elect ethical and competent sheriffs and county attorneys and hold them accountable.”
Finding that the death penalty "is imposed in an arbitrary and racially biased manner," a unanimous Washington Supreme Court has struck down the state's capital-punishment statute as violating Washington's state constitutional prohibition against "cruel punishment." The court's ruling, authored by Chief Justice Mary E. Fairhurst and issued on October 11, 2018, declared: "The death penalty, as administered in our state, fails to serve any legitimate penological goal; thus, it violates article I, section 14 of our state constitution." The decision also converted the sentences of all eight people on the state's death row (pictured) to life imprisonment without possibility of release. The court's action makes Washington the twentieth U.S. state to have judicially or legislatively abolished the death penalty, and the eighth to have done so this century. Governor Jay Inslee, who imposed a moratorium on all executions in 2014, hailed the ruling, saying, "Today’s decision by the state Supreme Court thankfully ends the death penalty in Washington. ... This is a hugely important moment in our pursuit for equal and fair application of justice.”
The court issued the ruling in the case of Allen Gregory (pictured, bottom row, second from the right), an African-American man sentenced to death for the rape and murder of a white woman. In declaring the death penalty unconstitutional, the court cited recent research that found Washington juries were more than three times more likely to impose a death sentence on a black defendant than on a white defendant in a similar case. "Given the evidence before this court and our judicial notice of implicit and overt racial bias against black defendants in this state, we are confident that the association between race and the death penalty is not attributed to random chance," the opinion stated. The opinion also cited "arbitrary decision-making, random imposition of the death penalty, unreliability, geographic rarity, and excessive delays" as systemic constitutional flaws supporting the court's decision.
Washington has not carried out an execution since 2010. King County Prosecutor Dan Satterberg said that the court's ruling had finally brought to an end "Washington's four-decade experiment with the death penalty." Satterberg, a Republican, who with Democratic Attorney General Bob Ferguson supported bipartisan legislation to abolish Washington's death penalty, said "I think the criminal justice system will be stronger without capital punishment." The abolition bill, which was the subject of legislative hearings during the 2018 state legislative session, passed the Washington Senate and the House judiciary committee, but did not receive a vote in the full House.
On World Day Against the Death Penalty, Malaysia Announces Abolition Plan, European Union Reaffirms Abolitionist StancePosted: October 11, 2018
Marking World Day Against the Death Penalty, the government of Malaysia on October 10, 2018 announced its intention to abolish capital punishment in the Muslim nation of 30 million people. A continent away, the Council of Europe and the European Union issued a joint declaration reaffirming Europe's "strong opposition to capital punishment in all circumstances." The European government organizations also urged their members to implement measures to prevent trade in goods that could be used to carry out executions. As worldwide abolitionist organizations marked the occasion to highlight the living conditions of prisoners on death row, Malaysian officials announced that the country plans to end its use of the death penalty in its entirety. "All death penalty will be abolished. Full stop," said Law Minister Datuk Liew Vui Keong. He said the measure has been approved by the cabinet to be considered during the next Parliamentary session, which begins on October 15. Communications Minister Gobind Singh Deo told the Associated Press, "This is part of our election pledge and also in line with the move away from capital punishment in the rest of the world." Malaysia currently holds about 1,200 people on death row, and mandates capital punishment for crimes including murder, drug trafficking, kidnapping, and terrorism. In their joint statement, the Council of Europe and the European Union called the death penalty "an affront to human dignity" that "constitutes cruel, inhuman and degrading treatment and is contrary to the right to life. The death penalty has no established deterrent effect and it makes judicial errors irreversible." A country must have abolished capital punishment as a condition of membership in the European government organizations, and the statement urged Belarus—the only European country that still uses the death penalty—to impose a moratorium on the death penalty "as a decisive step towards aligning the country with pan-European standards." The statement also called on member states to "continue taking effective measures to prevent their involvement, however indirect, in the use of the death penalty by third countries. .... In this context," the statement said, "the Council of Europe and the EU will continue promoting the 'Global Alliance to end trade in goods used for capital punishment and torture'." Europe's trade stance has directly affected executions in the United States, as European countries have blocked the export of lethal-injection drugs to the United States.
Two Texas prisoners took steps away from death row as state courts ruled in their favor on issues involving false or faulty scientific evidence and argument. On October 5, 2018, the Texas Court of Criminal Appeals (CCA) granted a stay of execution to Juan Segundo (pictured, left), directing a Tarrant County trial court to reconsider a claim of intellectual disability that the courts had previously rejected based on an unconstitutional, unscientific standard for measuring his functioning. Four days later, an El Paso trial judge found that prosecutors had “presented false and misleading evidence and argument” concerning the cause of death of a 19-month-old whom Rigoberto “Robert” Avila (pictured, right) had been convicted of killing, and recommended that the CCA grant Avila a new trial.
Texas had been set to execute Segundo on October 10. Segundo’s lawyers had long argued that he is intellectually disabled and therefore exempt from execution under the U.S. Supreme Court’s 2002 ruling in Atkins v. Virginia. However, the Texas courts had dismissed that claim, relying on a series of nonclinical factors—some based on the fictional character Lennie Smalls from Of Mice and Men—to say that Segundo was not intellectually disabled under Texas law. In 2017, in the case of Moore v. Texas, the U.S. Supreme Court ruled that intellectual disability determinations must be “informed by the medical community’s diagnostic framework.” The Court struck down Texas’s approach, calling it an “outlier” that created “an unacceptable risk that persons with intellectual disability will be executed.” In Segundo’s case, the CCA wrote, “[i]n light of the Moore decision and the facts presented in applicant’s application, we have determined that applicant’s execution should be stayed pending further order of this Court.”
The CCA stayed Avila’s January 2014 execution based on a new law giving prisoners access to the courts to litigate new evidence that their convictions had been based on false or misleading forensic evidence. His was one of the first cases sent back to a lower court for reconsideration under the 2013 junk-science law. In his 2001 trial, prosecutors argued that Avila had killed his girlfriend’s infant son. “There’s no other way the kid could have died,” they told the jury. New evidence showed, however, that the infant could have died from injuries caused by his four-year-old brother. Judge Annabell Perez wrote that this new evidence “probably would have led jurors to harbor reasonable doubt about [Avila’s] guilt” if it had been available at trial. In a prepared statement, Avila’s lawyers wrote: “The new scientific evidence creates a compelling case for Mr. Avila’s innocence, and a judge has now found that the verdict against him rests on false and misleading testimony. After spending 17 years on death row—and facing four serious execution dates—for a crime he did not commit, Mr. Avila is anxious to present the reliable scientific evidence to a jury.”
Governor Rejects Jurors’ Plea for Clemency for Edmund Zagorski as Tennessee Court Allows Lethal Injections to ProceedPosted: October 9, 2018
Ignoring declarations by six jurors in Edmund Zagorski’s 1984 trial that they would have spared Zagorski (pictured) if they could have sentenced him to life without parole, Tennessee Governor Bill Haslam rejected Zagorski’s petition for clemency on October 5, 2018. In conjunction with the Tennessee Supreme Court's October 8 ruling upholding the constitutionality of the state's lethal-injection protocol, Haslam’s decision moved the state closer to executing Zagorski on October 11. At the time of Zagorski’s trial, Tennessee law required jurors in death-penalty cases to choose between sentencing a defendant to death or risk the possibility that he could later be released on parole. The jurors in Zagorski’s case submitted sworn declarations in support of clemency, saying that they would have sentenced him to life without possibility of parole, rather than the death penalty, if they had been given the no-parole option. Juror Michael Poole told Nashville Scene, “Our concern was that at some point in time maybe this man would be released and could actually be out in society and commit such a crime again. ... [Zagorski] has paid a significant price up to this point, I feel, and the continuation of his imprisonment until he dies of natural causes I think is punishment enough.” Nancy Arnold, another juror, agreed. “[A]s far as the law was concerned, all we could do was what we did. We had no choice of life without parole. I would have definitely done that if it had been available.” Zagorski’s clemency plea was also supported by correctional officials who said he has been a model prisoner and has reformed during his 34 years on death row. Despite those statements, Gov. Haslam denied clemency, writing that “the jury in Zagorski’s case heard the evidence at trial and rendered a unanimous verdict in accordance with the law at the time and their duty as jurors. Ten courts, including the Tennessee Supreme Court and the Supreme Court of the United States, have reviewed and upheld the jury’s verdict and sentence, and the Tennessee Supreme Court has held that the addition of life imprisonment without the possibility of parole as a sentencing option does not affect previous verdicts.” The Tennessee Supreme Court on October 8 also removed a hurdle to Zagorski’s execution, ruling 4-1 that Tennessee's lethal-injection protocol is constitutional, and that prisoners did not prove an alternative was available, as required. In response to that ruling, Zagorski requested that the state execute him with the electric chair, saying, “I do not want to be subjected to the torture of the current lethal injection method.” In a statement, Zagorski’s lawyer, assistant federal defender Kelley Henry, said the Tennessee high court decision had left Zagorski to choose between “two unconstitutional methods of execution.” Describing the prospect of “10-18 minutes of drowning, suffocation, and chemical burning” as “unspeakable,” Henry said Zagorski found the electric chair to be “the lesser of two evils.” Zagorski is appealing the Tennessee Supreme Court’s decision.
Junk science is “enabling and perpetuating grave miscarriages of justice” in Texas death-penalty cases. So concludes Professor James Acker in his article, Snake Oil With A Bite: The Lethal Veneer of Science and Texas’s Death Penalty, published in the latest issue of the Albany Law Review. Acker’s article highlights the heightened risks of injustice from pseudo-science and junk science in capital cases in Texas, one of the few states that conditions death eligibility upon a finding of the defendant’s future dangerousness. Acker writes that, “at virtually every ... stage of the state’s capital punishment process,” Texas prosecutors “have alternately enlisted expert witnesses and scientists who have helped move accused and convicted offenders progressively closer to the execution chamber, and ignored or discounted scientific norms and developments inconsistent with securing and carrying out capital sentences. All too often, the determinations made in support of death sentences are of dubious reliability—including opinions and conclusions based on what many would agree to qualify as junk science—thus greatly enhancing the risk of miscarriages of justice ....”
Acker’s article discusses Texas’s long history of abusing expert testimony in support of execution, starting with the case of Estelle v. Smith, in which Dr. James Grigson — later nicknamed “Dr. Death” — evaluated Ernest Smith for his competency to stand trial, did not notify counsel of the evaluation, failed to advise Smith of his right to remain silent, and then testified in the penalty phase “that Smith was a severe sociopath, that his condition could not be treated, and that he ‘is going to go ahead and commit other similar or same criminal acts if given the opportunity to do so.’” The U.S. Supreme Court overturned Smith’s death sentence in 1981 for violations of his right to counsel and his constitutional privilege against compelled self-incrimination. Two years later, in Barefoot v. Estelle, the Court permitted the use of psychiatric predictions of future dangerousness, despite warnings by the American Psychiatric Association that such testimony was speculative and highly unreliable. Grigson went on to testify in 167 capital cases, repeatedly responding to hypothetical questions posed by prosecutors (even after he was expelled from state and national professional associations because of this practice) that defendants whose institutional records he had never reviewed and whom he had never evaluated were certain to commit future acts of violence. Texas has also misused expert mental health testimony in capital cases to falsely argue that capital defendants posed an increased threat to society because of their race or ethnicity, Acker writes. He describes the testimony of Dr. Walter Quijano, a clinical psychologist who testified in seven cases that defendants were more likely to pose a danger to society because they were black or Latino. The Texas Attorney General’s office ultimately conceded error in all but one of those cases. Duane Buck’s case, however, reached the Supreme Court, where Chief Justice Robert condemned Quijano’s testimony as “powerful racial stereotyping.”
The Texas courts also systemically disregarded scientific standards or otherwise abused expert mental health testimony in determinations of intellectual disability and competency to be executed, Acker says. In the case of Moore v. Texas, the Supreme Court declared Texas’s approach to intellectual disability to be unconstitutional and ordered a reconsideration of Bobby Moore’s intellectual disability claim. With the prosecution, the defense, and multiple mental health groups all agreeing that Moore is intellectually disabled, the Texas Court of Criminal Appeals nevertheless upheld his death sentence. Finally, Acker writes, the state’s approach to competency has been an outlier, deeming Scott Panetti — who had been “hospitalized more than a dozen times [for mental illness and] been diagnosed as suffering from schizophrenia, bipolar disorder, auditory hallucinations, and delusions of persecution and grandeur” — competent to stand trial, to represent himself, and to be executed. Texas “has alternatively coopted, disregarded, and subverted science and prevailing disciplinary norms of the mental health professions,” Acker concludes. “The death penalty in Texas, imbued with powerful symbolism and political significance, has succeeded not only in condemning offenders, but also the principled teachings of science. ... Science and politics are a deadly mixture, in the nature of snake oil with a bite.”
