Under U.S. law, simply stating “I was in fear for my life” is not legally sufficient to justify the use of lethal force by a police officer. While fear is a factor, it must be objectively reasonable based on the totality of the circumstances. The legal standard, established by the U.S. Supreme Court in Graham v. Connor (1989), requires a “reasonableness” inquiry that judges the action from the perspective of a reasonable officer on the scene, rather than in hindsight. 

Key requirements for justifying lethal force beyond mere subjective fear include:

• Objectively Reasonable Belief: The officer must articulate specific, tangible facts that caused them to fear for their life or the safety of others, such as a suspect brandishing a weapon, making violent movements, or posing an imminent, immediate threat of serious bodily harm.
• The “Graham Factors”: Courts evaluate reasonableness based on three main factors:
  1. The severity of the crime.
  2. Whether the suspect poses an immediate threat to the safety of officers or others.
  3. Whether the suspect is actively resisting arrest or attempting to evade arrest by flight.
• Imminence of Danger: The threat must be immediate. If an officer has removed themselves from danger (e.g., stepping out of the path of a moving vehicle), the legal justification for deadly force often ends.
• Proportionality and Last Resort: Policies often dictate that deadly force should only be used as a last resort when no reasonable, safe, and feasible alternative exists.
• Limitations on Fleeing Suspects: According to Tennessee v. Garner (1985), officers cannot use deadly force to prevent the escape of a fleeing suspect unless they have probable cause to believe the suspect poses a significant threat of death or serious physical harm to the officer or others. 

While an officer can state “I feared for my life,” this is considered a conclusion. Without supporting evidence to explain why that fear was reasonable in that specific situation, it is insufficient to meet the legal standard for justifiable, lawful use of force. 

U.S. Immigration and Customs Enforcement (ICE) operates under a use of force policy, last updated in 2023, that aligns with Department of Homeland Security (DHS) guidelines, emphasizing the “objectively reasonable” standard for using force. The policy mandates that officers, including Enforcement and Removal Operations (ERO) agents, prioritize the sanctity of human life, use de-escalation techniques when possible, and only apply the minimum force necessary to control a situation.
