Forensic examiners also use marks left on bullets to match them to particular rifles. The technique though lacks a solid base of examination and mistakes are common. The concept behind ballistics analyses is that the production and use of a gun produces distinctive tool marks inside the barrel, which are then imprinted on each bullet fired from that firearm. Forensic detectives measure bullet size to establish caliber, then check the direction of flick through marks and the extent of twist to be able to define the firearm’s manufacturer.To match a particular gun to a bullet, detectives’ test-fire the firearm with a new bullet and compare both shells under a microscope, observing for similar striations. Detectives can also inquire from computer forensic that recommend potential matches.
Although we use this method, there is no study that has proved definitively that fingerprints are unique. Similarly, it is not clear if finger prints change over a period of time or that they show a discrepancy subject on the amount of pressure applied. Furthermore, studies are needed to expose inaccuracy rates. The ACE-V technic depends on two or more detectives reaching the same result, but it does not require them to go the same way.
