Abstract

Some government agencies take the position that the results of gunshot residue from the hands of victims of shootings are not probative and meaningless. It is my opinion from experience in many cases that this is not the case and the results can mean life or death in some cases. Actual individual cases are described. The results of samples examined years ago with a small number of gunshot residue particles and reexamined recently shows the number and quality of particles that can be located and identified with modern equipment.
