"But now, as to how to break through the last layer of window dressing, from where to start, indeed requires careful strategic and technical consideration. We must neither rush nor act recklessly."
As soon as these words were spoken, Political Commissioner Li suggested, "Should we consider involving a psychological testing expert to conduct a lie detector test?"
"Perhaps we can find some clues from the suspect's reactions."
Mr. Hou nodded slightly but cautiously analyzed, "A lie detector test can certainly be done. As an auxiliary investigative tool, it has some reference value."
"But you also know, the results cannot yet be used as convicting evidence in court."
"Moreover, our problem now is not a lack of direction but a lack of physical or objective evidence that directly links the suspect to the case."
