What is a common characteristic of interrogation?

A common characteristic of interrogation is that it often requires persistence to extract full information. Interrogation is a process where an investigator engages a subject in a manner designed to elicit detailed responses, and this often involves asking probing questions and revisiting topics to encourage the subject to disclose more information.

Persistence is crucial because people may initially withhold information for various reasons—perhaps due to fear, anxiety, or a desire to evade answering straightforwardly. Therefore, the investigator’s ability to maintain a dialogue, create rapport, and continuously encourage the subject to provide more comprehensive answers is essential to uncovering the complete narrative or facts of a situation.

The other options, while they may present interesting ideas, do not accurately capture the essence of what interrogation entails. Conducting an interrogation in front of a crowd is not typical, as it can influence a subject's willingness to communicate freely. A written script is not generally used, as interrogators often need to adapt their questions and strategies based on the responses they receive. Lastly, while there are jurisdictions and situations where legal representation may be limited, effective and ethical interrogation practices are ideally conducted with respect to a person’s rights.
