SPs should assess an individual based on the person's what?

Assessing an individual based on their actions is crucial within the context of security training because actions provide the most reliable indicators of a person's intentions and behavior. Observing how someone interacts with their surroundings, how they respond to situations, and their general conduct allows security personnel to make informed decisions regarding potential risks or threats.

Focusing on actions enables security personnel to identify suspicious behaviors or signs of distress more effectively than simply considering factors such as physical presence, background, or reputation. While those other aspects may offer some context, they do not guarantee an accurate assessment of someone's current state or potential threat level. Actions reflect real-time behavior and can signal whether an individual poses a risk or requires intervention, making it the most actionable and relevant criterion for assessment in a security context.
