最近,山东滨城区发生了38起学生宿舍盗窃案,涉及资产20余万元。为了找出小偷,山东滨州学院5000多名本科男生全部被一一采血查验DNA。采集和比对DNA进行刑事鉴证是世界各国认同并广泛应用于司法活动的一种行为,而且实践证明,这也是一种有效的鉴定嫌犯的科学手段。但是,DNA鉴定技术现在也面临着挑战。这种挑战来自两方面,一是科学的,另一是伦理的。 Recently, 38 cases of student dormitory theft occurred in Bincheng District of Shandong Province involving more than 200,000 yuan of assets. In order to find out the thief, Shandong Binzhou University, more than 5,000 undergraduate boys were all one by one blood test DNA. It is an act of criminal identification that is collected and compared with DNA, which is accepted by all countries in the world and widely used in judicial activities. Practice has proved that this is also an effective scientific method to identify suspects. However, DNA identification technologies are now challenged. This challenge comes from two aspects, one is science and the other ethical.
