Which of the following is NOT a category of force?

The correct answer identifies "Unjustified force" as not a category of force because force is generally classified based on its justification and adherence to protocols established for law enforcement practices. Categories of force typically include a range of techniques that are authorized and taught to officers, focusing on both trained techniques and the appropriate application of those techniques under various circumstances.

A trained technique refers to specific methods taught to officers to manage situations effectively while ensuring safety. Dynamic application of a trained technique indicates how these techniques are adjusted and applied based on real-time scenarios, showcasing their flexibility and adaptability.

The notion of "Not trained but justified under the circumstances" suggests instances where an officer may use force outside of their training yet find justification based on the specific context. This circumstance recognizes the complex nature of law enforcement where immediate decisions may need to be made in high-stress situations.

On the other hand, unjustified force implies a use of force that does not meet the necessary legal or ethical standards, thus it cannot be categorized as an acceptable form of force in law enforcement as it undermines the principles that govern the use of force within police protocols. Therefore, it stands apart from the recognized categories of force utilized by trained law enforcement officers.
