It’s a common enough scene: Officers on-site, responding to allegations of a crime; the public milling about, curious and uncertain. An officer approaches, poses direct questions: What did you see? Where did they go? Can you give us a description of the suspect? A civilian, nervous, fumbles for an answer. The officer grows impatient, the demands for information more adamant. There’s tension in the air. Under a peppering of questions, the civilian clams up, and the interview is over.
