What is one factor that courts use to determine if coercion occurred during an interrogation?

When evaluating whether coercion occurred during an interrogation, courts take a comprehensive approach that considers multiple factors to assess the totality of the circumstances. The duration of the interview is significant; lengthy interrogations can contribute to a suspect's fatigue and discomfort, potentially leading to coercive environments. The number of officers present is also relevant, as a larger police presence may intimidate the suspect, making them feel pressured to comply with demands or statements. However, the use of deception or threats is particularly pivotal, as overt coercive tactics can directly undermine a suspect's free will, leading to involuntary confessions or statements.

Thus, courts recognize that each of these factors can play a significant role in determining if coercion took place, which makes "all of the above" the most comprehensive and correct answer. By considering all these elements together, judges can better understand the nature of the interrogation and assess whether the suspect's rights were violated under coercive practices.
