当今世界各国真正实行彻底无罪推定原则的，往往莫不赋予犯罪嫌疑人、被告人保持沉默的权利。但是，我国刑事诉讼法第 93 条规定：“犯罪嫌疑人对侦查人员的提问，必须如实回答。只是对与本案无关的问题，有拒绝回答的权利。”
Nowadays those countries in the world which truly implemented the presumption of innocence invariably provide the suspects or defendants rights to remain silent. However, in conformity with No.93 Provision in the Chinese Code of Criminal Procedure, suspects have the obligation to answer questions asked by investigators, while they have rights to refuse if the questions have no relation with the case.
我国司法实践中应当允许犯罪嫌疑人、被告人享有沉默权，如果犯罪嫌疑人、被告人被强迫进行供述，并且侦查机关以此为线索展开侦查工作，审判机关以此作为定罪量刑的依据，那将会犯程序性的错误，导致一些冤假错案的发生。
Our judiciary should permit suspects or defendants to bear rights of silence. If suspects or defendants are forced to confess, with which the investigators conduct detection as clues and with which judiciary declare guilty or take measurement of penalty as evidences, the procedural mistakes will be made which lead to unjust, false and erroneous cases.
