警察审讯犯罪嫌疑人的目的是查明案件的事实真相和获取诉讼证据。犯罪嫌疑人出于防御的本能和趋利避害的心理,总是想否认犯罪,逃避惩罚,因此,审讯不可避免地存在着激烈的对抗性,警察如果想用对待普通守法公民的态度和方法从有罪者中获得证明其有罪的信息,显然是十分困难的,因此,他必须使用一些技巧和策略。从我国的刑事审讯实践看,欺骗性方法也是被实际允许并不时使用的。这种方法在刑事侦查学上常被称为“审讯策略”,其实质是“利用对方的劣势和弱点进行的心战智斗”。 The purpose of the police interrogation of suspects is to ascertain the facts of the case and to obtain evidence of the proceedings. Because of the defensive instinct and the tendency to avoid disadvantages, the suspects always want to deny crimes and evade punishment. Therefore, the trial inevitably has fierce antagonism. If the police want to use the attitude and method of treating ordinary law-abiding citizens It is obviously very difficult to obtain the information proving his guilt from the guilty, so he must use some skills and tactics. Judging from the practice of criminal trials in our country, deceptive methods are also actually permitted and are not used from time to time. This method is often referred to as “interrogation tactics” in criminal investigation. The essence of this method is “to use each other’s weaknesses and weaknesses to make a mental war.”
