Chapter 7 - Equipment used for forensic firearm examination

Abstract

The equipment required for forensic firearm examination has remained relatively unchanged over time. Advancing technology has allowed for methods of bullet recovery to fit the needs of each laboratory setting in reference to cost and size. Additionally, the digitally dominated age of the 21st century has allowed microscopic examination to incorporate the digital camera with a simple click of the mouse. The methods for obtaining measurements, whether it is for length or weight, have relied on the accuracy of the measuring device as well as its reproducibility. As with any type of forensic analysis, the examination of a firearm and its related components cannot succumb to the fallacy of estimation: incorrect techniques or equipment can be the determining factor in a courtroom verdict. This is one of the several reasons why the core constituents of forensic firearm examination, for example, the bullet recovery method and the microscope, have changed only to allow for progressing technology.
