Which of the following resistance levels indicates the highest potential for danger?

Active aggression indicates the highest potential for danger because it involves an individual actively engaging in behavior intended to harm or pose an immediate threat to the safety of others, particularly law enforcement officers. This level of resistance demonstrates a clear intention to resist authority through physical means, which could escalate into a violent encounter.

In contrast, the other forms of resistance, such as verbal noncompliance and defensive resistance, while potentially challenging, do not necessarily imply an immediate threat of physical harm. Psychological intimidation, although it can create a tense situation, typically involves a display of confidence or aggression without direct physical action. Therefore, active aggression is recognized as the most serious form of resistance due to its direct confrontation and potential for physical violence.
