Which element is considered an extreme measure on the use of force continuum?

The element considered an extreme measure on the use of force continuum is deadly force. In law enforcement and military contexts, the use of deadly force is regarded as the last resort, utilized only when there's an imminent threat to life or serious bodily harm that cannot be resolved through lesser means. This represents the highest level of force, signifying that all other options have been exhausted or deemed insufficient to neutralize the threat.

Deadly force is distinctly different from other measures such as verbal commands, which are aimed at de-escalation and control, or chemical agents and empty hand control, which are intermediate measures of force. Each of these options typically involves a range of responses that are less lethal and allow for the possibility of resolution without causing permanent harm. Therefore, the necessity to resort to deadly force implies a critical situation where immediate and significant action is necessary to protect oneself or others.
