In the summer of 2013, a nineteen-year-old named Rachel Jeantel took the witness stand in Sanford, Florida, in the murder trial of George Zimmerman, the neighborhood watch volunteer who had shot and killed seventeen-year-old Trayvon Martin the year before. Rachel was the last person to speak with Trayvon while he was alive. She was on the phone with him as Zimmerman followed him through the neighborhood. She heard what happened. She was, by every definition, the prosecution’s most critical witness.
Defense attorney Don West seized on the fact that Rachel had initially withheld from Trayvon’s mother that her son had called the man following him a “creepy ass cracker.” This omission (a teenager trying to protect a grieving mother from language that might reflect poorly on the child she had just lost) was reframed by the defense as proof of Rachel’s fundamental dishonesty. West didn’t not focus on the “creepy,” rather the racial language of “cracker.”
West then trained his fire on her speech itself, highlighting their use of Black vernacular English and making a point of noting that Trayvon had ended a question with a preposition. His challenge to Zimmerman (“Why are you following me for?”) was apparently more disqualifying than evidence of his fear. The case briefly became less about homicide and more about sentence structure. The court reporter repeatedly interrupted her testimony, claiming she couldn’t understand the witness. The cumulative effect was a sustained, multi-front assault; not on what Rachel said, but on how she said it.
Rachel pushed back. When West tried to put words in her mouth, she refused. “That’s how I speak,” she told him. “You cannot hear me that well.” She arrived for two days of nationally televised cross-examination, endured it, and still walked away having been judged, in the eyes of much of the public, as less than credible.
None of this, argues Duke political scientist Candis Watts Smith, was an accident. It was a pattern. One with a four-hundred-year paper trail.
Inthis rigorously argued book, Black Evidence: A History and a Warning, Smith makes the case that America has spent four centuries perfecting a single art: delegitimizing Black testimony. Not as an accident of history but as deliberate policy, baked into law and hardened into cultural reflex. Smith (co-host of the Democracy Works podcast, author of Stay Woke: A People’s Guide to Making All Black Lives Matter and Racial Stasis, and whose TEDx talk on myths about racism has been viewed over two million times) brings that same gift for connecting political history to lived reality.
Her argument is sweeping, and the book covers a lot of ground. Across six chapters, Smith examines how the refusal to credit Black voices has rippled outward into every major American institution: the courtroom, the hospital, the laboratory, the schoolroom. She shows how Black witnesses have been recast as liars, Black patients dismissed as people who don’t feel pain the way others do, Black children treated as something other than children.
She frames all of it as a recurring American pattern: a moment of racial progress, followed by what Smith calls walloping retrenchment. From Reconstruction to redemption, from landmark civil rights legislation to the Southern strategy, from the multiracial protests of 2020 to the swift rollback of DEI policies, the cycle repeats. Smith’s contention is that this is not coincidence. It is the predictable result of a society that has never fully reckoned with whose truth it is willing to hear.
Smith’s implication is broader still: a society that systematically refuses to hear certain voices loses something essential in itself. The prescription that follows is direct: listen, take seriously, amplify.
The chapter called “Exclude” (on the systematic legal suppression of Black testimony) is where the argument hit me hardest. I ended up highlighting the whole thing.
When the Law Forbade Black Testimony
Smith begins where the rot begins: colonial statute. Laws like Virginia’s 1701 Act for the Better Ordering of Slaves didn’t just regulate the bodies of enslaved people; they regulated whose words counted. Enslaved Black people could neither testify against a white person nor serve on a jury. Maryland made its reasoning explicit, warning that admitting Black testimony could be of “very dangerous consequence” (dangerous, that is, to the racial order the law was designed to protect). There was one carved-out exception: Black people could testify, but only when doing so served white interests, particularly in cases involving suspected insurrection, where slaveholders needed shielding from financial liability for their “property’s” behavior.
The cruelty embedded in this system was almost literary in its irony. If an enslaved witness was found to have committed perjury, punishment could include having both ears nailed to a pillory and then sliced off, followed by thirty-nine lashes. As abolitionist William Goodell observed at the time, enslaved people were treated as mere property in every context except when they needed to be held accountable; at which point they were suddenly reconstituted as legal persons. Personhood was extended only when punishment required it. Accountability, it turns out, had fewer racial restrictions than testimony. The law had managed to invent a population that could be accused of crimes but could not speak in its own defense.
This exclusion was not confined to slaveholding states. It spread northward, westward, and eventually into the treatment of anyone deemed racially other. Smith points to the 1840 federal case United States v. Dow to illustrate just how elastic and opportunistic these rules could be. When a Malay sailor murdered the captain of a ship on the high seas (with only Black crew members as witnesses), the accused argued that Maryland’s racial exclusion laws meant those witnesses couldn’t testify against him. He was trying to weaponize the architecture of white supremacy to literally get away with murder.
Chief Justice Roger Taney, writing for the Circuit Court of Maryland seventeen years before he would declare in Dred Scott that Black Americans had “no rights which the white man was bound to respect,” denied the gambit. But in doing so he articulated the underlying rationale with chilling candor: non-white witnesses were barred, he wrote, because of their “barbarous ignorance” and “crude superstitions,” rendering them unable to grasp the weight of an oath in a Christian court.
The logic was circular and self-sealing, and Smith calls it exactly what it is: Black people were excluded from testimony because they were deemed untrustworthy, and their presumed untrustworthiness was reinforced by the exclusion itself. Declare someone untrustworthy. Forbid them from speaking. The exclusion then becomes its own justification.

After the Law Changed, Disbelief Remained
The law books moved on. The courtroom reflexes sometimes did not.
Smith’s return to the Zimmerman trial is the moment when the distance between 1701 and 2013 ceases to feel like distance at all. Suddenly the history lesson stops feeling like history. West showed no interest in extending good faith to Rachel’s effort to protect her dead friend’s reputation; he turned that loyalty into evidence of her unreliability instead. The trial asked who shot Trayvon Martin. The public conversation often asked whether Rachel Jeantel sounded credible enough to be believed.
Smith’s own assessment lands like a verdict:
“Rachel was allowed to sit and speak on the witness stand, but her testimony was made moot by constant interruptions, consistent castigation of the way she enunciated her words, and implied accusations that she was too incompetent and ill-educated to be a credible witness. Rachel was treated as if her testimony didn’t matter because, in fact, it had not.”
Meanwhile, Smith points out, Zimmerman’s own statements (that he was tracking down “fucking punks” who “always get away”) entered the record without anything approaching the same scrutiny. Whose fear registered as legitimate, and whose did not, was not a neutral question. Smith argues it never has been.
Black Evidence is not primarily a legal history, though it functions as one. It is a reckoning with how a nation constructs knowledge: who gets to be believed, whose account of events registers as evidence rather than noise. Smith is careful to note that the formal legal prohibitions on Black testimony are no longer on the books. But she is equally careful to show that erasing them from statute did not erase them from practice. As she puts it, the lingering legacy of exclusion continues its work as a deeply embedded American norm.
Reading about the Zimmerman trial now, through Smith’s lens, the trial looks different. It wasn’t just a case about one man and one night in Sanford, Florida. It was a demonstration of something much older: the presumption that some testimony arrives in court pre-discredited. Black Evidence is the history of how that presumption was built, brick by brick, statute by statute, over four centuries. Smith’s argument is that we cannot dismantle what we refuse to see. This book makes it very hard to look away.
