Lin Hao was being followed. Although the person was caught, Liu Bingnian interrogated them for a day without finding out who was behind it. Clearly, no coercive methods were used.
In fact, coercive interrogation isn't all that unusual even nowadays.
Since Liu Bingnian didn't resort to force, perhaps someone exerted pressure on him, or possibly bribed him.
When he called today, it was partly to deal with Lin Hao and partly to test his attitude.
However, Lin Hao wasn't a fool. He quickly figured out Liu Bingnian's intentions and voiced his discontent.
Although the police station belongs to the public security system and isn't directly under the jurisdiction of the executive vice county magistrate, as a standing committee member, Lin Hao still held real power.
Thus, upon hearing this, Liu Bingnian felt a sharp unease in his heart and immediately promised, "County Magistrate Lin, rest assured, I will definitely make him talk."
