On an average day around 96 Americans are killed with guns. When considering the topic of forensics, it can be viewed as a broad subject because of the fact that it has a vast amount of sub-categories. One of these primary categories of forensics is called ballistics which is described by Criminal Justice Degree Schools, “Forensic ballistics is the examination of evidence relating to firearms at a crime scene.” This research paper will explain how technology and ballistics go hand in hand to help solve crimes.
Ballistic experts recognize the many different marks that a firearm imprints on a bullet some identifications they make include rifling inside barrels, and other markings on the projectile itself. Experts often tend to model their scenes to receive better vantage points and points of impact. There are miniscule details in every bullet that experts examine to determine what model production it is, and chemical test to see what ammunition was used in the firearm. With every test ran on bullets after crimes ballistics become extremely complex dealing with numbers, angles, distance, and trajectory points. Experts analyze firing pin impressions, extractor marks, tool marks and ejector marks in shells and casings. They use comparison microscopes to compare bullet marks side by side to identify possible matches to casings.
Ballistics is considered a science, however for many years law enforcement and courts observed ballistics as redundant and non-significant in most major gun related crimes. With todays technological features ballistics have made a massive impact on evolving the science behind ballistics. Many scholars and researchers that work in ballistics bend over backwards to enhance the value of different ballistic research methods and improve efficiency for all forensic procedures. Physical laws are a main focal point in ballistics, starting with the Law of Ideal Gas. An ideal gas law as defined on a web article “Ideal Gas Law” “one in which all collisions between atoms or molecules are perfectly eleastic sic (elastic) and in which there are no intermolecular attractive forces”. Meaning that spheres of energy strike each other but do not interact with one another.
Ballistics is typically separated into three different areas: external, internal, and terminal ballistics. In order to deliver scientist adequate analytical instruments, the division was made to teach the study of separate ballistics to adapt features to become more effective. The division is based upon a pathway that the bullet takes down the barrel, through the air, and then the target. In the study of internal ballistics behaviors forensic scientist use velocity as a central standard measuring unit. Internal Ballistics “is to evaluate spatial, as well as time curves of velocity and pressure, with physical plausibility and possible precision, under a given set of loading conditions” (K. S. Bhaskara Rao, K. C. Sharma, 157).
Combustion residues, powders and pressures, energy transfer, along with weapon recoil are all general elements required to be known by forensic professionals. The precise moment that the bullet exits the barrel, the bullet converts into an object of external ballistics. According to the Washington State Criminal Justice Training Commission, ” External ballistics is the study of what happens to the bullet while it is in flight.” The way crosswinds alter missile trajectory is an additional topic of forensic research in external ballistics. Some numerical basis of external ballistics that turns ballistics into a field of mathematics dealing with geometrics and algebraic problems include bullet stability, density, shape, aerodynamics, and flight stabilization. Without researching the process and changes the bullet undertakes while encountering with an object, the study of external ballistics would become invalid.
The studies of ballistics that have previously been mentioned all fall into
terminal ballistics research.
“We have chosen to conceive of terminal ballistics as
a violent and extremely rapid confrontation between two forms of resistance
before the final state of rest is reached. This definition, which cannot help but don
the admittedly loud and outlandish garb of physics, is the most promising for the
purposes of biological interpretation” (Mangiante G, Dagradi V, Radin S, Carolo F, Giarolli M, Tenci A, Meric G, Acerbi A, Tosi D, Della Giacoma G). Terminal ballistics professionals collaborate to connect the relationship between target devastations and the flight of the bullet, design, velocity, and physical appearance of the target. Terminal ballistics is understandably the most complex, intricate, and greatly accounted area of topic for forensic scientist considering that the majority of cases that terminal ballistics investigates are human
