A survey was sent to 80 forensic laboratories in 44 States and two Canadian Provinces concerning methodology in analyzing gunshot residue (GSR) and interpreting the results. Of the 80 surveys, 50 (63%) were returned completed. Questions included standard procedures, collection methods, thresholding problems and specificity of data. These results are compared to a previous survey reported in 1990. Implications for the interpretation and future study of these methods are discussed.
