In practice , occasions when in vestigative organs misuse the power of investigation and encroach on the legal interests of the criminal suspects and other interested people often arise when the organs are implementing acts of investigation , for example , extorting a confession by torture in interrogating the suspects , or taking evidence by violence in inquire the witnesses 而从实践看，侦查机关滥用侦查权，侵犯犯罪嫌疑人和其它利害关系人合法权益的情形，往往就是出现在侦查机关实施侦查行为的时侯，如在讯问犯罪嫌疑人时刑讯逼供，在询问证人时暴力取证，进行非法搜查、扣押等等。
Part three : by drawing on the useful experience of the international community in preventing extorting a confession by torture and taking into account china ' s reality , measures are proposed for reducing and even eradicating extorted confessions by torture . the measures include giving suspects the right to silence , implementing the ideology of presumption of innocence , perfecting the rules for accepting evidences , strengthening legal constraints on criminal case investigators , and executing compulsory isolated interrogations of suspects and defendants by inquiring officers 第三方面：借鉴国际社会对防治刑讯逼供的有益经验，结合我国实际，提出减少甚至杜绝刑讯逼供的措施：赋予沉默权实施无罪推定理念、完善证据采信规则、加强对称刑事案件调查者的法律制约以及侦查人员对犯罪嫌疑人、被告人强制性隔离审讯等。
