Forensic Ballistics Most of us will have heard the term ballistics at some time or other-more often than not when we have been watching fictionalized accounts of police work on television or in the cinema. When you think of forensics you may think of something like “The Forensic Files”, “NCIS”, or even “Law and Order”. Although, ballistics is a part of forensics first we will look at forensics itself and how it came about. After getting the basics about the foundation in forensics we will look at ballistics and how the specifics of ballistics started, who is the founder as well as what ballistics consist of. To the best of my ability, we will review different types of test preformed by a ballistic analyst. After gaining all of the …show more content…
The “some-thing” left behind is the evidence that detectives and criminalists (people who make use of science to solve crimes) look for. It might be fingerprints, footprints, tooth marks, blood, semen, hair, fibers, broken glass, a knife or gun, a bullet, or something less tangible such as the nature of the wounds or bruises left on the victim's body, which might indicate the nature of the weapon or the method of assault. Careful analysis of evidence left at the scene of a crime often can be used in establishing the guilt or innocence of someone on trial. In the past called forensic ballistics, this forensic science concerns itself with the comparison and identification of crime scene bullets and shell casing firing pin impressions with the marks on test-fired rounds in the crime lab. If the marks on the bullet made by the test gun barrel are identical to the striations (rifling scratches) on the crime scene bullet, or the firing pin impressions are the same, the crime scene weapon has been identified. The science is grounded on the principal that no two guns will leave the same marks on the ammunition. Bullet striations and firing pin impressions are unique as a person's fingerprints. Firearms identification also involves restoring filed off serial numbers, retracing projectile flights, identifying the various types of bullet wounds, and determining the range of close range shots through powder stain patterns on the
