The Perth urban rail system, like many other rail systems in Australia and overseas, is subject to crime and anti-social behaviour around the railway environs from a small minority of the travelling public. The transit officers, who form part of the security section of the Public Transport Authority, are the people employed to deal with these incidents, which can result in transit officers being injured.

A spent cartridge case exhibits characteristic markings (firearm fingerprint) that can be used to identify the type and possibly make of weapon in which the cartridge was fired. This report details research into the use of discriminant analysis for the purpose of matching spent rim-fire cartridge cases to specific make and model firearms. The discrimination and classification are based on several scalar shape parameters for the two-dimensional silhouette of the firing pin (FP) impression-- shape factor calculated from the second order moment of inertia, G factor calculated from the distance transform, and the P2A factor- as well as the distance …
