Mell What are the problems associated with ballistic fingerprinting?
Problems with the ballistic fingerprinting technology Compounding the problem is the fact that the existing technology which helps trace bullets or their casings back to the guns that fired them is fatally flawed.
How reliable is ballistic fingerprinting?
The report included the test firing of more than 2,000 rounds from 790 pistols. When cartridges from the same manufacturer were test-fired and compared, computer matching failed 38 percent of the time. With cartridges from different manufacturers, computer matching failed 62 percent of the time.
What are ballistic fingerprints and how do they form?
Ballistic ‘Identification’ or Ballistic ‘Fingerprint’? Every firearm leaves unique, reproducible markings on each bullet and cartridge case it fires. These markings function as a “ballistic fingerprint.” Today, ballistic fingerprints are inadver- tent but unavoidable byproducts of the way most guns are made.
What is an example of ballistic evidence?

What is kept in ballistic fingerprint?

Are fingerprints individual evidence?
Properties that make a fingerprint useful for ID: It’s unique characteristic ridges which make them individual evidence. It remains unchanged during an individual’s lifetime.
What does it mean to do ballistic fingerprinting?
Ballistic Fingerprinting: about, techniques, bullet marking. The mechanical study of the launching, flight, behavior and effects (usually visual marks) of bullets is what ballistic fingerprinting usually refers to.
Can a background check be considered invasion of privacy?
Fingerprinting and background checks cannot be considered as invasion of privacy, but on the contrary, as one more means in order to make this life safe and law-abiding. With the help of such techniques, it is possible to clear up who is a real criminal and who is a victim.
Is it true that fingerprint identification is an accurate science?
