Specifically, it offers a scientific framework for analyzing high-profile cases over recent decades where unarmed Black individuals were killed by people who claimed they genuinely perceived the victims as armed or representing a threat to their personal safety.

Trayvon Martin was a 17-year-old African American high school student whose death on February 26, 2012, became a national focal point for issues of racial profiling. He was fatally shot by George Zimmerman, a neighborhood watch volunteer, who had identified Martin as suspicious and pursued him despite a 911 operator's instruction not to. Although Martin was unarmed, Zimmerman claimed self-defense and was ultimately acquitted of both murder and manslaughter. This verdict, combined with the circumstances of the shooting, triggered a nationwide outcry and widespread public demonstrations.

In 2019, Atatiana Jefferson was fatally shot in her own home by a police officer. A neighbor had placed a non-emergency call to police out of concern for Jefferson's front door being open late at night. An officer who arrived on the scene went to the back of the house. Jefferson, who was unaware of the police presence, retrieved her legally owned gun from her purse. The officer perceived a threat and fired through a window, killing her as her 8-year-old nephew watched.
