Which factor plays a significant role in determining if a suspect is free to leave?

The attitude of the officers toward the suspect is a significant factor in determining whether a suspect is free to leave. This is because the demeanor and conduct of law enforcement can heavily influence the suspect's perception of their freedom. If officers approach the interaction with a supportive or neutral attitude and communicate clearly that the suspect is not under arrest, the suspect is more likely to feel free to leave. On the other hand, a confrontational or aggressive attitude may imply to the suspect that they are not free to go, even if technically they are not being detained.

This aspect is particularly important in the context of the "reasonable person" standard used in legal assessments. The subjective experience of the suspect is often analyzed through this lens, meaning that how the officers interact with the individual can impact their sense of liberty and decision-making at that moment.
