A total of 43 officers were sampled with adhesive-lift discs, which were subsequently concentrated and analyzed by scanning electron microscopy with energy dispersive X-ray spectroscopy microanalysis. GSR levels on the officers' hands were lower than expected, considering that a firearm was carried and handled by all officers. Only three of the 43 officers had unique GSR particles. No officer had more than one unique GSR particle. Twenty-five of the 43 officers had no particles of GSR on their hands. Although the potential for secondary transfer contamination from an arresting officer to a subject exists, the low empirical numbers of GSR particles found on these non- shooting officers suggest that the potential for this occurrence is relatively low. 3 figures, 3 tables, and 15 references
