Abstract
The question of “accepted uniqueness” of several types of GSR particles is discussed. Based on our experience, we propose to include GSR particles formed in firing the Sellier Bellot, Prague (SBP) ammunition in the group of “unique” GSR particles. With the advent of autosearch systems for GSR analysis in crime labs, a better statistical basis for the extent of uniqueness of various types of GSR particles may be achieved.
