What physical action might suggest a subject is preparing to attack?

The clenching of fists is often a clear physical indicator that a subject may be preparing to attack. This action signifies heightened tension and readiness for a confrontational response. When someone clenches their fists, it can be a manifestation of anger, frustration, or aggression, which are emotions that frequently precede an aggressive action. This physiological response can serve as a warning sign to law enforcement officers, allowing them to assess the situation and prepare accordingly.

Other actions such as laughing or applying lip balm do not typically indicate an intent to engage in violence or aggression. Laughing may suggest relaxation or amusement, while applying lip balm is a benign action unrelated to physical confrontation. Similarly, ignoring commands can signify a lack of respect or noncompliance but does not necessarily suggest imminent physical aggression. Therefore, clenching fists stands out as a specific physical action strongly associated with the potential for an attack.
