目前,刑事现场的复杂多变和犯罪嫌疑人日渐具备反侦查能力,给现场勘查和案件侦查带来诸多困难和阻碍,采取单一技术手段或传统侦查方式难以满足侦破案件的需要。警犬搜索物证技术具备处置快捷、方式简便、定位准确和覆盖范围广等优势,与其它勘查技术和侦查手段相结合,能够为案件侦破提供更多支持。汕头市公安局在侦破刑事案件中大力推广和使用警犬搜索物证技术,取得突出成绩。
At present, the complex and changeable criminal scene and the suspects are increasingly equipped with anti-detection capabilities, which bring many difficulties and obstacles to on-site investigation and case investigation. It is difficult to meet the needs of detecting cases through a single technical means or a traditional detection method. The police dog search evidence technology has the advantages of quick disposal, simple and convenient method, accurate positioning and wide coverage, and other exploration technologies and detection methods to provide more support for case detection. Shantou Municipal Public Security Bureau vigorously popularized and used the police dog search material evidence technology in the detection of criminal cases and achieved outstanding results.
