Which factor is NOT assessed when determining the objective reasonableness of an officer's use of force?

The objective reasonableness of an officer's use of force is evaluated based on several key factors that relate closely to the situation at hand and the behaviors of both the officer and the suspect. Assessing the immediate threat posed by the suspect is crucial, as it helps determine the necessity and proportionality of the force used in response to that threat. The severity of the crime also plays a significant role; more serious crimes may justify a higher level of force if warranted by the circumstances.

Additionally, the officer's training background is relevant because it informs how an officer is expected to respond in various situations. Training can shape the officer's judgment and reactions, making it an important consideration in understanding their actions.

In contrast, the number of spectators present does not directly impact the assessment of reasonableness in the use of force. While the presence of bystanders may influence an officer’s perception of their actions or the atmosphere of the engagement, it does not relate to the immediate operational factors that dictate the necessity of the force used. Therefore, this factor is not considered in evaluating whether an officer's use of force was reasonable under the circumstances.
