On the opening day of his trial in Frisco, Texas, supporters of 19-year-old Karmelo Anthony—charged with the 2025 fatal stabbing of unarmed high school football player Austin Metcalf—clashed with counter protesters outside the courthouse. The defense's self-defense claim has drawn dueling crowds, while a lingering controversy over an all-white jury's empanelment has fueled accusations of racial bias.

Three schoolteachers and a jury of 12 white peers

According to the source article, prosecutors struck three potential black jurors because all three were schoolteachers, arguing that the case concerned a schhool and its policies. The judge agreed, resulting in an all-white jury empaneled over defense objections. The defense has accused the prosecution of racial bias, but prosecutors deny this, maintaining the strikes were based on professional relevance, not race.

This specific rationale—that educators might be predisposed given their workplace experience—has become a central flashpoint. The defense team continues to argue that the decision reflects systemic bias, while the prosecution insists it was a routine legal judgment. The trial's perceived fairness now hinges on whether the jury can weigh the evidence without the shadow of this selection dispute.

'Self-defense is not a crime' — the chant that defines Anthony's legal strategy

Video from the protests shows supporters chanting that self-defense is not a crime, echoing the principal defense being pushed by Karmelo Anthony's legal team. The accused allegedly argued with Austin Metcalf at the high school in April 2025, then pulled a large knife from his gym bag and stabbed the unarmed Metcalf in the chest, killing him, as the report states.. The self-defense claim directly challenges the prosecution's narrative of an unprovoked attack.

Outside the courthouse, the chanting has drawn counter protesters who question whether the stabbing of an unarmed student qualifies as self-defense. The public demonstrations illustrate how the legal argument has become a rallying cry, with both sides using social media to amplify their messages.. The case has sparked a heated debate about the boundaries of self-defense, especially when the alleged victim was unarmed.

Why the prosecution's 'schoolteacher' argument survived a challenge

The judge's decision to uphold the prosecution's strikes has been a key point of contention. according to the source, the judge agreed that the three black jurors being schoolteachers gave them a potential bias in a case involving a school. This rationale, while legally plausible, has drawn criticism from activists who accuse the prosecution of racial bias in jury selection.

Legal experts might point to precedent allowing peremptory strikes for job-related reasons, but the optics of an all-white jury in a case with a black defendant and a white victim are problematic. The broader context includes a highly publicized case where social media has already shaped public opinion. The unanswered question remains: did the prosecution's explanation satisfy the legal standard, or did it mask a discriminatory pattern?

A killing at Frisco High School that split a Texas community

The incident occurred at the high school in Frisco, Texas, where Karmelo Anthony and Austin Metcalf were students. The fatal stabbing of a star football player during a school day shocked the suburban community. The protests outside the courthouse reflect deeper divisions over race, justice, and the use of deadly force, even among teenagers.

Multiple factors are at play, including the role of the school's policies, the availability of weapons on campus, and the public's perception of the legal system. As the trial continues, daily demonstrations are expected, with supporters of both sides maintaining their presence. The outcome will likely have implications beyond this single case, influencing how similar self-defense claims are handled in school settings across the country .
