Mitigation

Mitigation is the work of making a person’s history and circumstances visible when a court decides how culpable that person is and what sentence is just. In Bryan Stevenson’s cases, it means investigating experiences often absent from the trial record—abuse, poverty, mental illness, disability, and failures of care—and explaining their bearing without pretending that serious harm did not occur. Its central distinction is between understanding an act and excusing it: the State may hold a person accountable and protect the public, while still taking disability and life history into account when determining the degree of culpability and punishment.

Purpose and Scope

Mitigation is not a substitute for evidence about whether a defendant committed a crime. Walter McMillian’s case makes the distinction especially important. On the day Ronda Morrison was murdered, a fish fry took place at McMillian’s home: church members and relatives were there through the morning, and McMillian and his mechanic friend had dismantled the transmission of his truck by 9:30. These details supported an alibi and a challenge to the accusation itself, not merely an argument for a lesser sentence. The contrast shows why evidence of innocence and evidence relevant to punishment must not be collapsed into one category. A person may need both a reliable inquiry into guilt and, if sentencing follows, a full account of the life and capacities behind the charge.

The book presents mitigation as disciplined investigation rather than a general appeal for sympathy. In Avery Jenkins’s case, the defense brought forward evidence that his trial lawyers had failed to uncover: his history in foster care, serious mental illness, and disabilities. At a three-day post-conviction hearing, experts described organic brain damage, schizophrenia, and bipolar disorder, and explained how these conditions could contribute to dangerous behavior. Their testimony distinguished the manifestation of severe illness from a judgment about Avery’s character. Evidence about foster care widened the inquiry beyond diagnosis: several foster parents were later convicted of sexual abuse or criminal mismanagement, while Avery had been passed from one unstable placement to another until he was drug-addicted and homeless.

Disability, Trauma, and Culpability

Avery’s history gave the court a concrete account of how vulnerability accumulated. At ten, abusive foster parents locked him in a closet, denied him food, and beat him; his foster mother later tied him to a tree in the woods and left him there. Hunters found him three days later in very poor health. By thirteen he was abusing drugs and alcohol; by fifteen he was having seizures and psychotic episodes; at seventeen he was deemed incapable of management and left homeless. At twenty, during a psychotic episode, he entered a stranger’s house believing he was under attack by demons and killed a man. The account neither removes the victim from the story nor makes Avery’s illness a metaphor. It supplies circumstances needed to assess the conduct and sentence with greater precision.

Stevenson argued that ignoring mental disability was as unreasonable as demanding that a person who had lost his legs climb stairs without assistance, or that a blind person cross a busy highway unaided. Physical disabilities are more readily recognized, he observed, while invisible mental disabilities are more readily dismissed as personal failure. The point was not that illness makes harmful conduct harmless. He explicitly acknowledged the State’s responsibility to hold a person accountable and protect the public; his objection was to disregarding disability when evaluating culpability and deciding punishment. The distinction places the question on the adequacy of the judgment, not on whether the harm mattered.

The hearing also showed how mitigation can address the conditions that shaped a person without reducing that person to them. Avery’s former foster parents admitted frustration because they were not equipped to manage his serious mental-health problems. Stevenson presented those failures alongside expert evidence, making the record about both Avery’s impairments and the environments that failed to accommodate them. His recurring effort to bring Avery a milkshake—an ordinary request the prison repeatedly denied—offered a small, concrete counterpoint to the enormity of the case: the person facing a death sentence remained a person with preferences and a relationship to others, not only a diagnosis or crime.

Childhood and Rigid Sentencing

Trina Garnett’s case shows what happens when a court cannot consider mitigation even where the circumstances are stark. She was the youngest of twelve children in the poorest section of Chester, Pennsylvania, where close to 46 percent of children lived below the federal poverty level. Her father, Walter Garnett, was a violent alcoholic who abused her mother, Edith, in front of the children. After Edith died, the abuse and desperate circumstances worsened Trina’s emotional and mental-health problems; when she became acutely distressed, relatives took her to a hospital, but she was never allowed to remain long enough to recover or stabilize.

In August 1976, at fourteen, Trina entered a row house through a window with her sixteen-year-old friend, Francis Newsome, hoping to speak with boys who lived there. Trina lit matches to find their room; the house caught fire, and two sleeping boys died of smoke asphyxiation. Their mother accused Trina of setting the fire intentionally, while Trina and Newsome maintained it was accidental. Traumatized and barely able to speak after the deaths, Trina was so listless that her appointed lawyer thought she was incompetent to stand trial. Yet he failed to pursue the motions and evidence needed for an incompetency determination and did not challenge her trial as an adult. Newsome testified against Trina in exchange for the charges against her being dropped, and Trina was convicted of second-degree murder.

The sentencing judge found that Trina had no intent to kill, but Pennsylvania law did not allow him to account for that finding at sentencing. Nor could he consider her age, mental illness, poverty, abuse, or the circumstances of the fire: mandatory life imprisonment without parole was the only sentence for second-degree murder. The judge expressed serious misgivings, but the law left no room for the individual history mitigation is meant to bring into view. Trina’s case therefore marks the difference between collecting contextual evidence and having a legal process capable of acting on it.

Victims, Remorse, and the Reach of Context

Mitigation does not belong only to defendants’ families, and it need not erase victims’ needs. After Herbert Richardson’s hearing, Stevenson encountered the mother of a victim, who explained that she and her daughters had been promised help they never received. One daughter’s hearing had never been right since the bomb, and another had nerve problems; she said that she and her daughters needed assistance too. Stevenson had no co-counsel, had just left a difficult hearing, and represented Herbert, not the family. He apologized gently for the help they had not received and clarified whom he represented. The encounter exposes a practical tension: attending to a defendant’s background cannot make the injuries suffered by victims and their families disappear, and a just response must be able to recognize both.

Debbie Baigre’s relationship with Ian Manuel offers another way that responsibility and a person’s capacity for change can coexist. On Christmas Eve in 1992, not long after arriving in prison, Ian used his monthly phone call to reach the woman he had shot. He apologized and expressed remorse. Baigre, who had physically recovered and was working toward a career in bodybuilding and a women’s-health magazine, was surprised by the call; it began a regular correspondence. After years of communication, she wrote to the judge who had sentenced him, arguing that his sentence was too harsh and his confinement inhumane. She acknowledged the destructiveness and recklessness of his crime while describing him as a thirteen-year-old with problems, no supervision, and no available help. The courts did not reduce his sentence. Her advocacy nevertheless makes clear that attending to a child’s circumstances need not require a victim to deny the harm: Baigre could name the crime and still challenge what was being done to him.

A woman whose grandson had been murdered described a different encounter with the limits of punishment. After the boys responsible were convicted and sent to prison forever, she expected their sentences to ease her grief, but instead felt worse. At trial, another woman sat with her for nearly two hours; for well over an hour they said nothing, and the bereaved grandmother remembered the presence as meaningful. The scene does not provide a sentencing rule, but it places punishment beside an actual account of grief and care. In the book’s treatment, mitigation belongs to a wider insistence that the needs of harmed people cannot be reduced to the severity of a sentence.

Learning to See Mitigation

The concept also changes through explanation and encounter. After Avery’s hearing, a correctional officer who had previously treated Stevenson harshly told him that the expert’s account of permanent damage to children in abusive homes had made him worry. The officer had looked up the word mitigation after hearing Stevenson use it in court. He said he had not understood the term at first, but now did, and told Stevenson he had done well. Their quiet conversation and handshake turn legal vocabulary into a question that reaches beyond the courtroom: what it means to understand the conditions from which another person comes, and to acknowledge that everyone needs mitigation at some point.

The book’s argument is that a sentencing judgment is incomplete when it records only the act and omits the life that preceded it. Mitigation asks courts to make that life legible, especially when disability is invisible, trauma is treated as irrelevant, or mandatory rules prevent a judge from considering age and circumstance. Its moral force lies neither in denying accountability nor in promising that contextual evidence will always change an outcome. Avery’s hearing and Trina’s sentence show both the possibility of a fuller account and the limits imposed when the law refuses to use it. The practice insists that a person can be responsible for grave harm and still be more than the worst act attributed to them.
