刑事诉讼的基本任务是打击犯罪与保障人权,无论是打击犯罪还是保障人权,都离不开证据。由于一些民警缺少证据学知识,在收集证据过程中存在不知道、不重视、不规范、不守法等现象,加之刑事案件自身的特点,导致基层民警在侦查取证中存在不少问题,同时也遇到一些难题,这不仅影响对犯罪的有效打击,而且阻碍对人权的保护。 The basic task of criminal procedure is to crack down on crimes and safeguard human rights. Both the crime-fighting and the safeguarding of human rights can not be separated from the evidence. Because some police lack evidence to learn knowledge, there are some problems in the process of collecting evidence, such as ignorance, neglect, non-compliance and non-conformity. Combined with the characteristics of criminal cases, there are many problems in the investigation and evidence collection by grassroots police, To some difficulties, this not only affects the effective crackdown on crime but also hinder the protection of human rights.
