What is the primary condition described in Tennessee V. Garner Prong 4 for using deadly force?

The primary condition described in Tennessee v. Garner regarding the use of deadly force is that it must be necessary to prevent the escape of a fleeing suspect who poses an immediate threat to the safety of officers or others. This ruling emphasizes that deadly force should only be used in situations where it is deemed essential to prevent serious harm or death, and where no reasonable alternative exists to prevent the suspect from escaping. The decision serves as a constitutional safeguard, ensuring that the use of deadly force is not arbitrary, but rather a measure of last resort under specific and grave circumstances.

In contrast, the other options highlight situations where deadly force may seem justifiable but do not align with the criteria set forth by the ruling. For instance, claiming that deadly force is acceptable if less lethal options are unavailable does not address the necessity principle required by Garner. Similarly, stating that deadly force can be used simply because a suspect is armed or if the officer feels threatened does not meet the established requirement of an immediate threat to life. Thus, the correct understanding hinges on the necessity to prevent escape in a context where there is a substantial risk of serious harm involved.
