What is a common sign that may suggest a suspect is preparing to resist arrest?

Clenching of the jaw or teeth can indicate a heightened state of tension or aggression in a suspect, and it can be a physical manifestation of their intent to resist arrest. This behavior is often accompanied by other signs of anxiety or aggression, such as a rigid body posture or increased breathing rate. Physically, a clenched jaw may suggest that the individual is preparing to react in a confrontational manner, making it a key indicator for law enforcement officers that the suspect may be planning to resist action.

While turning away may indicate avoidance, and making verbal threats suggests aggression, these behaviors do not always correlate directly with physical readiness to resist. Requesting help might imply a desire for assistance and would typically not indicate resistance. Clenching the jaw shows a more immediate readiness for conflict, making it a significant indicator for officers to be aware of during an encounter.
