Interrogation is psychological warfare, and yet it's more than that.
Especially during the pre-trial examination, ninety-nine percent of criminal suspects can't withstand this phase.
However, not all suspects have a weakness, so those who do withstand it are quite a few in number.
Generally speaking, suspects who haven't committed capital offenses are the easiest to get a confession from.
Since they've already been caught, being honest and striving for a lighter sentence is the most sensible approach.
Some murderers, after committing their crime, always feel they can get away with it, but in reality, under a seasoned pre-trial examiner, it only takes a few words before they become illogical and contradictory.
The toughest situation is when the evidence is insufficient and the suspect refuses to speak.
Take Wu Congwen, for example.
Wu Congwen's identity was confirmed based on the fingerprints collected by Lu Chuan near the edge of the water trough at Zhao Dong's cattle pen.
