Which of the following situations would require a NOT trained but justified approach to force?

Situations that require a "not trained but justified" approach to force occur when individuals find themselves in unexpected or unforeseen circumstances where they must protect themselves without having the benefit of prior training to handle that specific scenario.

In the case of self-defense during an unexpected encounter, an officer or individual may find themselves in a situation where immediate action is necessary to protect themselves from harm. The individual would not have had the opportunity to prepare or train specifically for that encounter, yet the need to respond swiftly and effectively justifies the use of force. This can stem from the element of surprise, caught off-guard by an aggressor, necessitating a justified but untrained response based on instinct and immediate assessment of the threat.

The other situations, such as a perceived immediate threat, active resistance, and a pre-arranged confrontation, typically involve scenarios where training is provided to deal with those situations in a controlled manner. Here, individuals can apply techniques and strategies they've learned during their training, making them fundamentally different from the suddenness of an unexpected encounter.
