Studying the Feasibility of Bringing In Independent Agencies to Support Verifying the Scene of a Traffic Crime Scene

Abstract

           This research aimed to: (1) examine the model, structure, and roles of independent agencies in supporting the forensic examination of traffic crime scenes; (2) study the legal principles and relevant statutes concerning traffic crime scene examination in Thailand; and (3) analyze legal problems and obstacles related to the involvement of independent agencies in supporting traffic crime scene examination, as well as propose legal development guidelines consistent with international standards. This study employed a qualitative research approach, using documentary research together with in-depth interviews with five key informants, including inquiry officials, forensic scientists, academics, and legal experts. The data were analyzed using content analysis.

           The findings revealed that an appropriate independent agency should serve as a technical and professional support mechanism in the forensic examination of traffic crime scenes. Its structure should consist of a crime scene investigation unit, a forensic laboratory analysis unit, and a digital forensics or accident reconstruction unit. Such an agency should operate under international standards and a strict chain of custody system. However, current Thai law still lacks clear provisions defining the legal status, roles, and authority of independent agencies. This creates limitations regarding the admissibility of examination results in court proceedings and the credibility of forensic evidence. The findings indicate the need to develop a legal framework and regulatory measures to systematically support collaboration between state agencies and independent agencies. Such development would enhance the efficiency, transparency, and fairness of traffic crime scene examination processes in Thailand.
