What is the definition of deadly force?

The definition of deadly force is accurately represented by the statement that it involves the intentional use of a firearm or other instrument that would result in a high probability of death or great bodily harm. This is because the concept of deadly force encompasses actions taken with the understanding that they could lead to lethal outcomes.

In law enforcement and self-defense contexts, the use of deadly force is justified only under specific circumstances, such as when there is an imminent threat to life or serious bodily injury. The defining characteristic is that it poses a significant risk, exceeding mere harm or injury, which aligns with the distinction of great bodily harm or death.

The other options do not meet the criteria for deadly force. Non-lethal instruments or actions that lead to minor injuries do not describe situations where there is a strong likelihood of causing death or serious injury, which is the essence of deadly force. Additionally, using a firearm in self-defense against unarmed individuals does not inherently warrant the use of deadly force, as the necessity and proportionality of force must be assessed based on the threat level. The core understanding of deadly force centers on the severity of the outcome, clearly emphasizing serious harm or fatality as its defining feature.
