What is the difference between "reasonable force" and "excessive force"?

The distinction between "reasonable force" and "excessive force" is fundamentally rooted in legality and justification. Reasonable force refers to the level of force that is necessary and appropriate in a given situation, meaning it is legally justified and recognized within the confines of the law. This type of force is typically considered appropriate to address immediate threats, defend oneself or others, or to perform lawful duties.

On the other hand, excessive force occurs when more force is used than is necessary to subdue a situation or protect oneself. This type of force goes beyond what is acceptable under the law, making it legally unjustifiable.

Understanding this difference is vital for law enforcement and others who may need to employ physical force, as using excessive force can lead to serious legal consequences, including civil liability and criminal charges. Therefore, the core of the correct answer highlights the legality of the actions taken and the appropriateness of the force in the context of the situation at hand.
