This chapter discusses general concepts in the investigation of shooting incidents with an emphasis on the reconstruction of events that occur at such scenes using a comprehensive approach that includes pre- and post-shooting incident considerations. Considerations for the forensic scientist are numerous in shooting incident reconstruction, but are not widely discussed in the literature. To this end, the author has attempted to organise the discussion into a chronological progression of considerations that include: 30 1) a philosophy of the critical thinking; 2) an introduction to various specific shooting incident/firearms related phenomenon that offer reconstructive information integrated with other forms of physical evidence; 3) practical approaches to reconstructive techniques that can be applied during the direct investigation of shooting scenes and/or resolving reconstructive issues that inevitably arise after the fact; and 4) practical considerations gleaned from a review of sources from both investigative and/or physical evidence prepared by various professionals in law enforcement and forensic science.

It saves time and money since the desensitisation step and the use of a dark room facility are avoided. The performances of several commercial inkjet papers were evaluated (77,78). Though some of the tested papers are not suitable, others give better results than traditional black-and-white photographic paper; moreover these papers do not interfere with 37 Firearms the Sodium Rhodizonate Test (77), often used in conjunction with the Modified Griess Test. Nevertheless, these chemical techniques usually necessitate the GSR to be transferred to a support and so are destructive to evidence.

Mahoney et al. (98) used Time-of-Flight Secondary Ion Mass Spectrometry (TOFSIMS) to characterise the organic composition of unburnt propellant powders. Smokeless powders, black powders and black powder substitutes were analysed. Positive results were obtained in analysing all additives in smokeless and black powder, both organic (like ethyl centralite, dibutyl phtalate and nitrocellulose) and inorganic (like potassium nitrate, potassium perchlorate and sulfur) in nature. Using Principal Component Analysis (PCA), the samples could be clustered in the different groups they belong to, showing the applicability of the technique in this field.
