Deadly Force as Self Defence

An interview with Prof. Kimberly Ferzan

The law of self-defense permits the use of deadly force under a strict set of conditions: the threat must be both imminent and unlawful, and the response, both necessary and proportionate. But what of the murkier scenarios where multiple parties, ensnared in the throes of perceived danger, believe themselves justified in their fears? Consider the tragic case of George Zimmerman and Trayvon Martin—where does the law stand when fear is misplaced, and how swiftly can one lawfully escalate to lethal force? Professor Kimberly Ferzan of the University of Pennsylvania School of Law navigates these shadowy waters and others offering her insights into the delicate balance between legal theory and the stark realities of personal safety.

Professor Ferzan uses the high-profile cases of Ahmaud Arbery to shed light on self-defense laws, particularly focusing on the contrasts between "duty to retreat" and "stand your ground" statutes. These distinctions highlight how one's legal obligations during a confrontation can vary significantly from state to state. She clarifies the roles of aggressors and provocateurs in these scenarios—those who initiate violence yet claim self-defense when faced with retaliation, revealing the layered complexities and rapid judgments required by law.

Professor Ferzan explores Kyle Rittenhouse's case to discuss how guns can further complicate self-defense claims. The presence of a firearm can, on the one hand, necessitate a quicker escalation to lethal force, legally justified by the potential threat of the weapon being used against its owner. On the other hand, bringing a weapon into an already tense situation can potentially be seen as a provocative act, influencing the legal framework (and public opinion) on what constitutes legitimate self-defense. Thre notorious examples and hypotheticals, Ferzan sheds light ont the interplay between legal principles, ethical considerations, and the real-world implications of defensive actions.
