Not all interrogation approaches are like that. For example, the Reid Technique is nothing like you describe, and would probably be exceptionally good at implanting false memories (and is known to lead to false confessions).
This isn’t an approach (that’s a specific term in interrogation), this is Direct Questioning. There are many approaches but I wasn’t talking about them here. Approaches are used to gain rapport and trust with people who would rather see you dead.
You use direct questioning once you’ve succeeded at your approach, when you lose trust, or when you’re not trained properly on approaches because you can fuck it up pretty bad.
