在司法实践中,利用“线人”或特情举报或提供情报来破案和抓获犯罪嫌疑人并不是个别现象。由于对“线人”法律规制上的欠缺,加之国家机关在使用线人侦查中也疏于规范和管理,中国目前“线人”的使用存在严重的失范现象,线人侦查中暴露出许多亟待解决的问题。总结中国的实践经验,借鉴外国的立法,建立与完善中国的“线人”制度已成为一个不容回避的话题。 In judicial practice, it is not an isolated phenomenon to use “informants” or special reports or intelligence to solve criminal cases and arrest criminal suspects. Due to the lack of legal regulation of “informants” and the lack of standardization and management by state agencies in the use of informants, there is a serious anomie in China’s use of “informants” Exposed many problems to be solved. It is an unavoidable topic to sum up China’s practical experience and learn from foreign legislation to establish and improve China’s “lineman system.”
