Gunshot Residue (GSR) analysis cannot be overemphasized in firearm shooting investigation, hence gaining popularity in forensic ballistics recently. This article critically reviews the study conducted to ascertain possible presence of GSR on population not directly involved in the discharging of the weapon. The study sampled detainees at Police station whose criminal charge was not connected to firearms. It employed GSR analysis technique to determine presence of particles. From the findings, it was concluded that GSR is unlikely to get transferred to different surfaces. This article therefore scrutinizes the whole study to validate its findings. It discusses the strength that would make finding worth adopted and shortcomings that would not necessitate the adoption [1].
