Which tactic aims to lull a witness into a false sense of security during cross-examination?

The tactic that aims to lull a witness into a false sense of security during cross-examination is friendliness. This approach involves creating a rapport with the witness, making them feel at ease and more likely to provide information that may not be advantageous to them when answering questions. By using a friendly demeanor, the attorney seeks to foster a trusting environment, encouraging the witness to let their guard down and perhaps inadvertently disclose details that could impact the case. This tactic is strategic in nature, as it contrasts sharply with more aggressive or confrontational methods, which can lead to defensiveness or resistance from a witness.
