What is one key requirement for using deadly force according to Tennessee v. Garner?

According to the ruling in Tennessee v. Garner, a key requirement for using deadly force is that there must be a significant threat of injury to others. This landmark case established that police officers can use deadly force only when they have probable cause to believe that the suspect poses a significant threat of death or serious physical injury to the officer or others. The court emphasized the importance of assessing the risk posed by the suspect before resorting to such extreme measures. This requirement helps to balance the necessity of enforcing the law with the protection of life, ensuring that deadly force is not used lightly but only in situations where there is a clear and present danger.
